Neanderthal a period of about 2,900,000 years passed and yet there was no real advancement in all of that time, and we can see this because the tools that we have discovered of the two species remain virtually identical. Then about 35,000 years ago modern man suddenly arrived on the
scene. Where did he come from so quickly? How is it possible?

There is no "pure" or "unpure theory". A theory is still a theory, and does not warrant the status of fact until all information is present to deem it so and all alternative possibilities bearing contrary evidence have been exhausted.
Some scientific explanations are so well established that no new evidence is likely to alter them. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact.
