You seem to be confusing "theory" with "hypothesis".
They aren't the same.
If there were scientific evidence against the theory of evolution, it wouldn't be taught in school. It would have to be changed or discarded.
There is evidence against the theory. here are some things to consider.
1. Natural selection is not a strong enough force to have changed us from bacteria to humans even over a zillion years. How come other animals/beings (like other bacteria) havent changed? What was wrong with their natural selection?
2. The idea of evolution just being completely random doesn't wash. There has to be an Intelligent Force controlling it.
3. There was an issue with the propellors on the first organisms (one-celled.) The organism could not exist without the propellor, it could not survive, but the propellor had to have been brought about by natural selection, which couldnt have happened unless the organism was alive, which it couldnt be, if it didnt have the propellor.
4.According to the theory of evolution, in the distant past there was no life in the universe -- just elements and chemical compounds. Somehow, these chemicals combined and came to life. How'd that happen, what caused it, what caused that, and how did the chemicals and other elements get there?
5. Why do we still have appendixes?
6. If evolution is caused by mutations, why are most mutations malignant and negative?
7. "Darwinists claim that the reptile-to-mammal evolution is well documented. But for reptiles to evolve into mammals at least some of these transformations must have happened:
• Scales had to have mutated into hair.
• Breasts had to have evolved from nothing.
• Externally laid eggs had to evolve into soft-shelled eggs that were nourished by an umbilical cord and placenta in a womb.
• It has never been observed in any laboratory that mutations can cause one species to turn into another. Despite this, evolutionists believe that given enough time, some animals will eventually evolve into other creatures.
• Sir Fred Hoyle, of Cambridge University stated that statistically the chances of one cell evolving was the same as a tornado passing through a junkyard and giving you a fully functional Boeing 747.
--There are many creatures that defy evolution. All of the examples below illustrate complex and sophisticated biological structures. It is difficult to believe that these creatures could have evolved, since all of their systems had to have been in place at the start for them to survive. Angler Fish; Chicken Egg
Beaver; Giraffe
Black And Yellow Garden Spider; Incubator Bird
Bombardier Beetle; Woodpecker
