One way in which Genesis correctly predicted what science has found is what is now known as the “Big Bang”, when the universe was first created. The current estimate for when that happened is about 13.7 billion years ago. 

Genesis 1:1 states this creation event very clearly and simply. 

In the beginning, God created the heavens and the earth.
Genesis 1:1

Genesis 1:1 states that a Creator who is outside of the universe created this universe. The Creator is beyond the universe that was created.
