Is there a credible scientific theory that opposes evolution? ? i need on this, it's for a journal but i need info that says we evolved from chimps next they'll say we were once birds and can fly

There is no credible science.

Explanation:

The fossil evidence is undeniable,  the only people that deny evolution are religious groups such as creationists who are a group that believe that the earth is only 3000 years old. Some parts of Christianity believe that dinosaurs don't exist because it isn't in the bible. The first fossil was found in 1819, so before the bible was written. In the bible, Genesis 1:31-35 God created the world and everything on it for man, nothing about dinosaurs or evolution leading people to believe everything was created to be the way it is and that it didn't evolve that way.
