Everyone on earth has asked this question in their life. How did we get here, what or who made us, and what is the meaning of life?
If we really did come from a chance explosion that produced a rock which morphed into a pile of cosmic slime 14 billion years ago, which slowly turned into this magnificently indescribably perfect system... Then life has absolutely no meaning whatsoever. That is, "IF"...
But the fact of the matter is: Our life did not originate from an explosion or monkeys. Rather, the God of the Bible spoke this all into existence, and knit your very being into existence while you were in your mother's womb. God created us to worship and give glory to Him, and gave us free in order to do so. (Making robots that have no choice but to worship and glorify you wouldn't be very glorifying now, would it?)
So, the true meaning of life is this: To give your life entirely to God and live for Him so that you may be useful, and to bring as many as possible to Christ.
Probably not the answer you wanted. But I'm not here to give people the answers they want, I'm here to give them the answers they need.
