I got to the part where you said evolution is "cyclical (back and forth)" and stopped reading. You quite obviously do not understand evolution at the fundamental level if you think it is cyclical. Evolution marches in one direction: forward, unto fitness. It is not cylical. Is it undisputable fact? No, of course not. That's what makes it a theory: it is, by definition, disputable and open to refinement when we have gleaned the requisite knowledge (unlike dogma). But it's the best damn explanation for how genetics change in populations overtime that we've come up with so far. And it's been replicated in labs under controlled conditions, as well as being observed across many species in nature. Thankfully, Science doesn't give a shit about your personal beliefs. It is true whether you believe it or not. The explanations may change, but the underlying systems and phenomenon they try to explain are unwavering.
