Who were the first aliens to visit Marvel and DC earth?

[Riv86672]

The Celestials visited Marvel earth 5 million years ago and were responsible for creating the Eternals, Deviants, and, I believe(?), mutants. Did any aliens show up prior to them?

And, no idea who might be the answer for DC...

DC: it depends. DC has mashed up its history so many times, there's no way to tell.

Prior to 1955, it was Superman.
Between 1955-1986, I haven't read enough Silver Age to say for sure.
Between 1987 and Nu52, it was maybe The New Gods (Byrne wrote some stuff about Mr. Miracle tooling around in the Old West).
Since then? Not a clue.

ETA: if you consider The Lords Of Order alien, it maybe Nabu The Wise.

For DC, probablyHunters/Gatherers from the PAD Aquaman who hunted the dinosaurs to extinction.

Didn't aliens grant caveman Vandal Savage his immortality and vastly enhanced intelligence? I forget which aliens they would be, though.

I thought his came from a meteor.

You're right. I could've sworn the meteorite was some sort of experiment by aliens, but according to wiki, nope!

I remember something about a prehistoric man captured by an alien spaceship that then fused with him, giving him immortality and enhanced intelligence in Byrne's Alpha Flight. Was that what you were thinking of?

The first aliens to canonically visit earth in the DC Universe might have been the White Martians who were responsible for depriving the human race of the super powers they initially had

I was thinking something similar.
I remember Vandal Savage and his tribe(?) battling a Burning Martian in the past.

It seems to me there used to be lots and lots of stories about aliens coming to Earth in the far distant past and many stories that said the gods were actually aliens. But I guess all that isn't considered continuity.

What about the Guardians of the Universe and the Manhunters. They would have been active millions of years ago. Even if Earth was just a mudball with water creatures in its ocean, wouldn't some alien from Sector 2814 have stopped in to check on the place just in case the universal evil was up to no good there?

Weren't the Beyonders (from Ka Zar and more recently Secret Wars) first?

Until somebody introduces The Even More Most Powerful Race, probably so.
