In fact, there's evidence to suggest "we" may have absorbed the neandertal lineage through interbreeding rather than simply supplanting them:
National Geographic | Neandertals, Modern Humans Interbred, Bone Study Suggests
LiveScience | Humans and Neanderthals Might Have Interbred
And yet another theory suggests we're the "odd man out." (No pun intended.)
"In the broader sweep of human evolution, the more unusual group is not Neanderthals, whom we tend to look at as strange, weird and unusual, but it's us, modern humans," Trinkaus said.
Source | LiveScience | Scientist: Humans Strange, Neanderthals Normal
Which might suggest to some that our evolution was "tinkered" with or "helped along" by some as-yet-to-be-determined outside force.
Hmmm, maybe a kick in the DNA by "God," "Reptilian," or "Alien?"

Cool!
So, not unlike Arthur Conan Doyle's "The Lost World," (not Michael Crichton's reconstituted dinos) there may be currently living "fossils" besides the coelacanth.
Very Cool!
Even if true, though, I don't think that fact would necessarily support the theory of "creationism."
