Science doesn't deal in proofs.
Try to rephrase your question in scientific terms. Besides the list I just posted has speciations, which necessarily

Your problem in understanding science is based on misunderstandings of the definitions and methods science uses.
You are adhering to the first rule of propaganda, "when you are unable to answer a question, throw a lot of data at the question and claim that it is an answer."
