This does not augure well for the evolution theory. We keep seeing new species appearing seemingly out of nowhere instead of one specie evolving into another...
This is all just wrong. Nothing depends on humans being descended from Neanderthals. There is a minor question whether modern humans ever interbred with the cousin branch of Neanderthals, hardly the same thing.
And if you routinely see something called a new "specie" popping out from nowhere, you should stop drinking whatever you're drinking.
Neanderthal fossils were catalogued over 100 years ago. If you point is that because we did not evolve out of neanderthal then evolution is weakened, look at it this way. Canids (dogs, wolves etc) evolved from an earlier species but they did not necessarily evolve from one another linearly. Foxes and wolves may have been on separate branches but derived from the same roots. LIkewise Homo Sapiens and Homo Neanderthalis, although doubtless related, they could simply have evolved from separate branches. Another analogy would be that you and your 3rd cousins are related but don't share the same parents or grandparents.

No, both appear to have a common ancestor.
They were different branches on the same tree.
On the contrary, science can see a path between each kevek if hominid evolution. You just didn't look into it.
But then again, what does creating multiple hominid species, some roaming the earth at the same time, all with varying levels of intelligence and capabilities, with all but one doomed to die out say about intelligent design? Why not get it right the first time? Why design failure after failure? Maybe you should change the name to "Damn, Let Me Try That Again" Design?
Not true. See the following Phylogenic tree:
