People are more dominant because of our mental adaptations. Evolution takes hundreds of years to produce a totally new trait in a creature, to give the creature the edge of that environment. The reason humans are dominant is because we figured out the system, and worked around it. We evolved mentally if you will, at a MUCH faster rate than the rest of the world, which put us far ahead of the physical evolution of everything else. THAT is why we are dominant.
Stars I personally know nothing about, but I imagine it's because there is only rougly 6,000 years of recorded history, since the 4th century BC, with the coming of written language. So supposing humans have been around two to three thousand more years than that, 9,000 years is totally miniscule in comparison to the geological clock, a mere blink in the history of the universe.
You can't debate the fact that the world is a shitload older than what the bible says, for the Earth CERTAINLY hasn't been around for only 2,007 years, and we know this for certain because of carbon-dating, which tells the age of something.
