” The burden of proof is always on the one saying something occurred. “
It is a proven theory. Up to you to disprove.
I’m aware of nothing that proves evolution. Certainly not the fossils, which is what ignorant people believe.
“It is a proven theory.”
Theories are never “proven”. To say such a thing just reveals your ignorance of science.
A theory can be confirmed to various degrees by observation and experiment, but with the major tenets of evolution, experiment and direct observation on the time scales necessary to achieve confirmation is impossible, so all that is left is indirect observation, looking at the historical remnants of the processes in question. The types of science that rely on that are always going to be only tenuously confirmed, at best, since our ability to determine historical conditions is always going to be incomplete and highly speculative.
Then would it still be a theory?
