Will they one day show us how to harvest energy that is beyond our wildest imaginations?
What I mean is, they must have an incredibly advanced energy source from which they draw upon, compared to us who still use fossil fuels as our main source of energy.
If aliens have indeed visited Earth, then what energy did they use to travel impossibly large distances across space? I am really interested in aliens because of how advanced they seem. Maybe they can teach us something.
