Here's what you're missing: In a chain of evolutionary sequences, there are more than just one link. There's no such thing as "the" link, or "the missing" link, there are multiple stages of transition, and it's possible to find one of them in 1995, a different one in 2002, etc.
The transitional sequence from our common ancestors with the other apes to modern humans has long been fleshed out to a very good degree, contrary to what the anti-evolutionists would have you believe. But with each passing year, yet more "intermediates of intermediates" are being discovered, like this one, which refine the transitional sequence to an ever more fine-grained degree.
And then there's the overwhelming DNA evidence...
Except to the willfully ignorant (see my tagline) any "debate" over the common ancestry of man and the other apes has long been over, it has been established beyond any reasonable doubt, via huge amounts of multiple independent lines of cross-confirming evidence.
Wrong. You have absolutely no idea (or proof) that any species is exclusively originated from this planet.
You are saying the earth is the center of the universe...
Now, go ahead with all of the gratuitous insults for creationists - - before your poor memory recalls that I am an atheist...
