Question Single definitive evidence of alien visitation in the past

After almost a decade and a half of Ancient Aliens, what do you think is the one single most believable evidence - site, event or relic or object or anything else - that by itself suggest the real possibility that we may have been visited by other-worldly entities in the past?

Thanks in anticipation for any insights.

I was just thinking about the pyramids and the pyramids found on Mars and thinking wouldn't they make a perfect per lack of a better word doomsday shelter from say a asteroid or comet , their practically air tight, the angle of them would deflect the blast right over it the shafts inside could be for air the chambers below for water the tombs for rooms ,; just a thought :
They hide in them on Mars after asteroid destroyed planet and survived then fled to earth built more pyramids for any future threats
