Atheists, you say the Bible is not true, how do you explain that it does indeed coincide with science?

God supossedly said "Let there be light..." about 4000 years ago and the Big Bang occured 12 to 15 billion years ago. How in the hell do you figure that they coincide? Besides, the Big Bang has absolutely nothing to do with the suns (light) forming. Please read a sccience book first before you make more of a fool out of yourself.
