A hypothesis is an educated guess. A scientific theory is a substantiated, unified explanation of nature that is supported by a vast body of evidence.

You're splitting hairs on semantics to hold onto your untenable position that evolution is not scientific.

I'll be impolite and say you don't know what you are talking about. And I will not wiki 'theory' for you.

Every aspect of the theory of evolution is falsifiable. To falsify "Non-avian dinosaurs perished at the end of the Mesozoic Era", you just have to find a dinosaur fossil from a later era.

Of course, even if we found a perfectly preserved fossil of a T-Rex from two million years ago, it likely won't falsify the whole theory of evolution, because there are simply too many evidences for that. It would be like saying "We found evidences that George Washington did not in fact die in 1799! The whole theory of the American Revolution is now in question, and the Aliens-did-it theory should be considered as good as the mainstream version!"

Strongly recommend you read Dawkins' "The Greatest Show on Earth" (https://www.amazon.com/Greatest-Show-Earth-Evidence-Evolutio...) and come back to tell us what you think :)

Do you believe in bacteria acquiring antibiotic resistance?

Do you believe in mutation?
