Natural Selection is a process. It describes how different species are formed from DNA.
Charles Darwin discovered Natural Selection. And Natural Selection has been confirmed by the sequencing of DNA.
Natural Selection was not designed to produce us.
I understand you believe God created the universe and everything in it. So as you are a Christian you believe that God the Father, God the Son, and God the Holy Spirit created the Big Bang. We have just recently measured, observed and analysed the background radiation of the Big Bang, not once but twice, with even more accuracy the second time. And there is not a fingerprint, a signature or a message in the Big Bang from God the Father, God the Son, and God the Holy Spirit. In short, there is no evidence the Trinity created the Big Bang.
But just pull back a little and consider what you believe. You believe a three headed God created the Big Bang. This is not only preposterous but also amusing.
Who created the DNA which Darwin has just discovered? The intelligent nature, you call it nature I call it God that's the difference..
It was not DESIGNED: I'm glad you used that word buddy.
yeah it was NOT designed it comes naturally, yet our human brain couldn't figure it out until like billion years later, so why do you think everything should be subjected to your human brain when there is much powerful brain that is beyond the ability of human brain, human brain is just discovering and trying to figure things out..
As for the Big Bang, ok this "Bang" should have been something that actually bangs, some material, where did that material come from anyway? There must be a time where it wasn't there at all right? I don't buy that it was just there I'm sorry..
And of course any theory can NEVER be proven by evidence unless we test it by actual experiment, which is almost impossible just like finding an actual God being hiding here or there and saying: Hey you found me you wicked witch!!
So if you just think it's how it is (Big Bang or any other creation theory) , then that would make you and Darwin and any other atheist an actual believers just like those who believe in God..
