"To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to "scientific method", ("scientific method", Oxford Dictionaries: British and World English, 2016).
Marty you have just made statements that are not based on empirical (verified by observation) or measurable evidence.
Vertebrate fish first appeared about 530 million years ago. Dinosaurs lived and evolved from 250 million years ago (where is the observable or measurable evidence for 250 million years?) and lasted until about 63 million years ago (who observed this?) - that's 187 MILLION years they lasted for.
When they bit the dust it allowed mammals, including our ancestors, to evolve. They didn't come down from the trees until 2 million years ago (where is the observable or measurable evidence for 2 million years?), and our own particular species has only been around for about 200,000 years (where is the observable or measurable evidence for 0.2 million years?).
We are literally a flash in the pan on geological timescales. We may continue to evolve and eventually leave the planet, we may disappear in an extinction event of our own making in the near future. Either way the Earth will survive and life with it, and when an ecological vacuum appears, something WILL evolve to fill it. Eventually, in 4 or 5 billion years, our sun will use all its fuel and become a red giant before collapsing into a white dwarf, effectively ending life on Earth.
We can only conclude that this is your belief system.
