Life on Mars?

Excuse me for butting into this conversation but I have some questions of my own I'd like answered in this relm of conversation. I've read about the "out of Africa" theories on how we originated there and migrated in 2 waves across the Earth. My questions are these, (1), if we did mrigrate from there, Why aren't we all negroes? What I'm asking is, where did Neandertal man come from? They were light skined, heavily built people, unlike us. The current theories don't answer the question of where all the races of humans came from very well. If humans migrated out of Africa, why did the negro race stay there and all the rest left? Then,the is the religeous aspect of another question that has always intriged me. If God created Adam and Eve... That mad two people on the planet. They had 2 sons which then made 4 people. One son killed the other and then there were only 3 people. Cain was banished from Eden and still there were only 3 people. How and with whom, did Cain father children? Myself, I don't think we're getting the whole picture from any side and that's a shame. I,for one, think that humans have been on Earth far longer than we think and have reached heights of civilization as great, if not higher than we are now,but,do to Tectonic catyclisms as well as celestrial ones the proof has been destroyed or most of it.

If this is true then explain to me the envirnments that would cause humans to have the pigmentations there are. If the Indians migrated from Asia, then there would still be Indians there also but there aren't. I've been to most parts of this planet in my service travels and haven't seen any part of it that would make for different pigmented humans. If caucasions were once black then they would still carry the sickle cell to some degree. Natural selection takes miilions of years to happen doesn't it? If not, then my question is still... Why aren't we all Negroes? Yes, I may have funny ideas, but my questions are never answered very well. There a few evidences that exist today that humans are far older than believed. Take for example, the sandaled footprints found beside dinosaur prints in 70 million year old rock. The suposition of envirnment doesn't hold up up in the migration theory to me because 50-75 thousand years isn't time enough to change that much. If it were, then by now Chimpanzees and gorillas would be evolved more also and start migrating themselves.

To make a comment on what degrees I hold was not relevent to my questions. Unlike most well educated people, I'm not blinded by science or religeon. If you take your sunlight answer and think about it, then Eskimos would be black because they live where it's light 24 hrs a day for almost six months. Having Black skin in a sunny envirnment doesn't make sense because darker skin would hold and absorb heat. You would think the further north you go the darker humans would be to help preserve body heat. And, yes the is such a thing as human footprints in 70 million year old rock. Go to Texas so see them in person. it is documented. along with other anomalies as old as that. It is the attitude of most scientists to disregard or outright not believe evidence that is right in front of them because it doesn't fit their doctrines. A case in point would be NASA's constant representations of Mars's envirnment. The Skies of Mars are blue, not pink and the True color of the soil is desert brown not rust red. Think about it... If there were enough iron on Mars to turn the whole Planet rust red then the Gravity would be higher due to more planetary mass. Sorry, I am well educated but I'm not blinded or except things just because someone else says it. Here's a good question for you. When the solar system was younger the sun was hotter. to hot for life to exist on Earth but maybe on Mars it was cooler. Why couldn't Humans have evolved there and migrated to here as the sun grew cooler? It is a possibility.
