How long have Caucasians been on our planet?

Question:

How long have Caucasians been on our planet?

What is the birth record of White people on planet earth ? It is said that they migrated from Africa but we know that African people are Black.

Some say that they came from Monkeys or some type of Ape like creature... Is this true? A common racial slur is to call Black people "monkeys" or "Apes" so are they really trying to say that they came form Us? The Cave man is only six thousand years old but there is no birth record for Black People on this planet. That is why I formed the question the way I did referring to the planet as "ours".

Even the languages that Caucasians speak are considered relatively new languages in comparison to the languages of the Original people of the planet.
