What would be acceptable "evidence" for you, then?
I don't know. What do you have? I learned about evolution and decent from a common ancestor in HS and College. My teachers lied and misrepresented the evidence. My text books were full of misinformation and fraudulent proof. If there was real evidence for decent from a common ancestor, Im confident that it would be taught rather than the usual lies and frauds that are regularly taught to students.
You know a theory is in trouble when they have to use the circular logic of homologies as evidence.
