it has alot to do with everything... heres some application for you..

Christopher Columbus didnt ever step foot on North America, it was infact SOUTH America where he landed, the first possible known person to step foot on America, was Leif Ericson, and it was around 1000 AD, others say it was possibly Richard Muerig, and others say John Cabot, both in the very late 1400s... carbon dating of crap (litterally) shows that Native Americans were here 14+ thousand years ago, but, they had Asian lineage in their blood lines...

so if you want to get technical, Asians were here first... immigration and evolution is part of the world, and part of history, you cant change it, what is true? how would we know, all we have to rely on is what people have written in books, so who is right? where do you start? because books are proven wrong all the time, and Albert Einstiens theory of "nothing is faster than the speed of light" is actually in the process of being disproved, as they have found molecules from atoms i believe that travel far faster than the speed of light...

the last part of that is rather irrelevant.. but it goes to show, that you can believe what you wish, there are many theorys, by many different people, whos right?

answer, noone really knows, because you werent here 500, 1000, 10000, 15000 years ago...

i was just trying to have a discussion, if people wont allow that, feel free to delete this now... i wont be hurt in any way....
