Recent finds indicate that modern humans may have originated as far back as 350 000 years, and most agree on "at least 250k". Source: http://science.sciencemag.org/content/358/6363/652

What? Evolution is both a theory and a fact? And we have evidence of this? You mean a scientific theory isn't the same as the colloquial use of the word theory? Next you'll be telling me there's proof the flat Earth isn't a viable explanation.

Well if we are a product of natural causes, there is no good or evil and when we die its the same state as before you were born. There is a transcendent good and evil, its good to love your family and evil for someone to shoot up an elementary school for example. This comes from God as we all carry the image of God. Why do I believe? I had a supernatural encounter that Jesus is lord. I believe in reformed theology and TULIP because its the most consistent with reality and what it would mean for God to be sovereign. The bible paints a picture of monergism and Calvinism lets those scriptures speak for themselves. This video is interesting but its basically intellectual mastbatory material for non believers no offense. "Look we spawned from nature randomly with the processes's just existing!!! there is no God or trasendent meaning, purpose, good and evil!!" Okay if thats true then this convo and my faith doesnt even matter in the end. Your not making the world a "better place" and in your world view making the world a better place doesnt even matter. We will all not exist in 50 years or so without memory or awareness of those we left behind or existing in the first place.

​+Shane McCausland _"No I believe God exists because I have had a supernatural encounter with the lord."_ You do know though that a supernatural encounter that convinces you that God exists means as much to the rest of the world as if a person had an encounter with aliens that abducted him, or somebody saw bigfoot in the forest. That's the thing with personal encounters. Or to put it differently: you experienced something, and you intellectually surrendered, sacrificing reason and logic to find the true answer, and instead went for something else. _"Anyways the lord fullfilled prophecies"_ 1) Prophecies got no dates. Why? Because anybody can make any kind of prophecy without a date without ever being wrong. Example: _"The world will take the shape of banana. Soon."_ Same as with _"Judgement Day is coming... soon"_ we could wait thousands of years without anything happening and I could just say _"yeah maybe tomorrow"._ 2) The Bible contains failed prophecies. That proves it wrong (together with all the other stuff, like a global flood, a boat housing billions of animals, people getting 600 years old, flat Earth and so on). 3) The prophecies in the Bible are only correct if you interpret them loosely enough. Here an exaggerated example: Bible: "And when the sky is dark the three volcanoes will erupt and the world will drown in bunnies." Apologist: _"Well... it was night, so it was dark. And it was only two volcanoes, but one was surely beneath under the earth. And with "drown" they just meant half a dozen and I saw one bunny and the rest of the dozen was probably nearby. Prophecy fulfilled."_ 4) Even if all prophecies in the Bible were correct, it would not prove that the christian deity exists. It could also have been the result of another deities works. Or no deity whatsoever. Maybe a highly advanced race of aliens is just mocking you. How would you know? By claiming that the prophecies prove God, you just again intellectually surrender and just go for whatever you like to be true instead of what is true.

+Hm Grraarrpffrzz No I believe God exists because I have had a supernatural encounter with the lord. He also revealed to me that the bible was his word, the next morning without knowing I had received the spirit of God my mother is banging and shouting in joy claiming God told her to read me a bible scripture. Did you interact with the rest of my comment? Anyways the lord fullfilled prophecies and thats what he gives to the unbeliever. That combined with good and evil with the majesty of creation all are held accountable to God with a burden to submit to him, even tho Romans 8:7 clearly says this demand is not even possible for you to fullfill in your flesh state. John 6:37-40 Jesus explains their unbelief in him claiming that God himself is the one who gives his sheep to him and that he will raise them up on the last day. Once again monergistic theology of the bible not the synergistic system that gets represented a lot of the time.

+Shane McCausland _"Isiah 7 talks about a virgin giving birth to a son, and he will be called Immanuel. This is what the angel said Jesus would be called in the gospel, it means God with us."_ In other words: There is a book. You believe that everything in the book is true, because it's the word of God. You believe that God exists, because the book says so. Question: what evidence do you have that the Bible more than a story collection?
Shane McCausland (23 дня назад)
+Hm Grraarrpffrzz Sigh I posted a long reply to everything and my comment bugged out. Ill keep it simple ~Isiah 7 talks about a virgin giving birth to a son, and he will be called Immanuel. This is what the angel said Jesus would be called in the gospel, it means God with us. ~Isiah 53 clearly shows a man being crucified as a sin offering for his people. "For he bore the sin of many, and made intercession for the transgressors." Thats Jesus. ~Psalms 22 Jesus quoted it going to the cross. "They pierced my hands and my bones were on display." So even when he died willingly, hes pointing towards the scripture to show how hes fulfilling this prophecy. "They divide my cloths from among them and casts lots for my garment" thats Jesus. "All the ends of the earth." Here you can see its not talking about israel or the hebrew people. Its talking about gentiles. "Will remember and turn to the lord". We remember Jesus and turn to the lord. "He has not despised or scorned the suffering of the afflicted one. Notice its in the same chapter as this particular man described being crucified. Jesus is the afflicted one described here. ~You have these fullfilled prophecies. The early church was persecuted and Christianity almost did not survive. Liars make poor marytrs. But the scriptures had many authors and went through a free transmission process. The bible was considered to be holy scripture in widespread areas very quickly. We can see this in the first council. They did not debate what was biblical cannon, but did request 50 bibles to be made with the books we consider inspired cannon today. ~I was not raised into the faith. I come from a broken home and my mom did not convert until I was 15. I used to mock her and ask why would she believe in a fairy tale 2000 years old. She just replied with I will pray for you. Which were prayers were answered as I was drawn to Jesus in secret and received a supernatural revelation similar to acts chapter 2. Before that revelation I did not read scripture and didnt know any bible verses. I converted and confessed my faith because I encountered Jesus. We can go through apparent contradictions with the bible if you want one by one. But yeah Jesus said no sign will be given to a wicked and adulterous generation who seeks one except for the sign of the prophet jonah. That is the message of the cross and fulfillment of prophecy written 1000 years before Jesus was born.

Great video guys, or videos. But when you talk about the endosymbiosis (minute 8:16) "one cell ate but didn't digest" another cell, there is a question... how could that cell self-replicate? regarding how did the development of internal new acquired organelles (mitochondria) get their own mitosis during cellular division.. or how did the new organelle get sequenced in the DNA of the cell so all new descendents will have mitochondrias? i know its a hard question, is there any info about it?

I don't think you're technically correct about the carbon dating a 4:46. The half-life of C is 5,730 years so after around 50,000 years it becomes unreliable. From https://scienceaid.net/Zircon_Dating the method used to deduce around 4 billion year old zircon crystals is probably another form of radioisotope dating, likely Pb-U.

This presentation did not mention the Ediacaran Period. The upper boundary of which is the only period boundary delineated by trace fossils (a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself) indicating the evolution of movement nor does it mention the evolution of bio-mineralization which is why the Cambrian "explosion" was interpreted as such by humans instead of simply the Cambrian radiation which is a more accurate description. Soft bodied fossils are very rare and go much further back in time. Making them rarer still.

I seriously doubt earth is the only planet with life. A very good percentage of stars actually have planets in their habitable zone, and have liquids that make abiogenesis possible. So it’s very likely that life is on other planets, we just haven’t found them yet. With the sheer number of planets and stars out there, I find it hard to believe that we’re alone in the universe.

Well, that's an incredible number of factors that have come together at the right time for our species to arise. Beyond grass coming at just the right time, there's the fact that the size of our planet is in a goldilocks size (large enough to hold an atmosphere, small enough that we can escape the gravity with chemical propulsion), the distance of the moon being perfect for regular solar eclipses and tidaly locked ... Either the simulation argument is correct or we really are one of the first species in the galaxy or perhaps the universe to get to this point.
Sam George (3 месяца назад)
Earth may seem perfect, but when there are literally trillions of planets out there, at least some are going to be habitable.
