Aliens In The Past

If aliens can interact with Earth in the present or the future, then why not also in the past? But the interactions must have been covert unless they was in an alternative past. Harry Turtledove has aliens openly invading Earth during World War II but, of course, that happens in one of his alternative histories.

"The Interloper" by Poul Anderson
The High Crusade by Poul Anderson
The Saga Of The Exiles by Julian May
The Known Space History by Larry Niven
The Lords of Creation novels by SM Stirling

I know that there are more examples than these but maybe not many. As with other topics, like time travel, Poul Anderson appears more than once on the list.

Kaor, Paul!

I like that notion, non humans from other planets visiting Earth in the past. And I would have included Anderson's "Peek! I See You!" in your list. Because the aliens in that story had been secretly visiting Earth for centuries.

And the Wersgorix aliens who came to Earth in the England of Edward III's were almost all killed nearly immediately when they foolishly attacked Sir Roger and his men in THE HIGH CRUSADE. And the unexpected disappearance of Sir Roger and his entire household and village meant no evidence was left behind to be found.

One thought I had about Julian May's SAGA OF PLIOCENE EXILE was that aliens came to our Earth so long ago that no evidence of their existence was likely to be found by the time Homo sapiens evolved into sentience.

Paul and Sean:
Andre Norton's Time Traders series (first book in 1958) begins with a U.S. time-travel project in the 1980s trying to discover how Soviet time-travelers are finding high-technology devices thousands of years in the past. It turns out the Reds are scavenging from alien starships that crashed on Earth, fifteen millennia ago or thereabouts. And then the extraterrestrials find out about the looters, and are unhappy enough not only to come here in force, but to chase them through the time gates into the present....

"Remember that hush-hush bang in the Baltic early this year? That was the 'space patrol,' or whatever they call themselves, putting finis to the Red project. So far as we know they didn't discover that we were and are interested in the same thing." (from the second book)

Kaor, DAVID!

I don't think, alas, I've e ever read Norton's "Time Trader" series. I do recall, from the time I was reading some of her works stories about "Forerunners." That is, stories about powerful alien civilizations of the remote past.
