[Lovecraft Mythos] What's the fall out off all this stories about ancient aliens in newspapers and scientific journals?

In more then one story the protagonist is left alive and with detailed reports of all ongoings with scientific accuracy (At the Mountains of Madness was a scientific expedition conducted and documented properly, leaving lots of details, evidence and at least one witness), or they even have flat out evidence for there stories (A Shadow out of Time ends with the protagonist having a millennia old book made out of unknown metal and paper written in modern English, confirming his account) and more often the stories end with a remark that further exploration and evidence gathering will be happening.

How did society react to the fact that apparently a race of ancient aliens lived and colonised the Earth millions of years ago?

In Lovecraft's stories, the encounters usually render the narrator insane, so the rest of society probably just ignores them. How could you believe in such unfathomable, impossible creatures without seeing them with your own eyes? And even then, you would still not understand them.
