The Bible is quite credible. If you don't think it is then prove Genesis 1 and 2 didn't happen.
If you'll read further on that site you'll see that science substantiates Genesis. It isn't taught in science classes because academia has rejected creation.
Are these the hard facts you supposedly needed from God? Okay, so how did you go about testing Genesis, something that supposedly happened 6000 years ago.
Hold on let's see.
1 In the beginning God created the heavens and the earth.
How did you go about testing this hard fact?
2 The earth was without form, and void; and darkness
wasfnon the face of the deep. And the Spirit of God was hovering over the face of the waters.
How did you go about testing these two facts?
3 Then God said, “Let there be light”; and there was light.
How did you go about testing these two facts?
4 And God saw the light, that
it was good; and God divided the light from the darkness.
How did you go about these two facts?
Oh wait, you didn't. All these "hard facts" you have never tested. And can't. Because it happened supposedly 6000 years. And according to your own admission, there's no one to test something that happened that long ago. We can't date things to see if they around that age according to you.
