> The million year forecast isn't "optimistic"; while it may be unlikely that human beings would be around for 5 billion years, your particular argument for that point is, well, based on one controversial claim and a couple of unjustified claims that don't follow from that controversial claim.
Where's the refutation of my point that we will have entirely disappeared in a million years, replaced by some other species? This isn't a philosophy debate, where words like "controversial" and "unjustified" carry weight among people trained in critical thought.

"Unjustified" always carries weight among people trained in critical thought, at least, when its true -- i.e., no adequate support has been provided for the conclusion presented. You've simply asserted that humans have been around for only 200,000 years as a species (which is one of two common viewpoints about H. sapiens, though "humans" in this context usually means the genus Homo and not the species H. sapiens -- 500,000 is the other, because where exactly at what point H. sapiens becomes a distinct species is debated), and jumped from there to the conclusion that H. sapiens will be replaced in another 200,000 years and that nothing similar will be around in a million years. Neither of those conclusions follow from the premise, which itself is less-than-certainly correct.
