How will society be affected if aliens came and gave us advanced technology millions of years ahead of our technology?

Millions of years advanced? About the same way a marmoset would be affected by being told how computers work. Even an ancient Roman would take a few years just to understand how the internet is being used by people - the basic concepts everyone grew up with just aren't there.

Aliens a few thousand years advanced? Since, at least according to Einstein (and I'm not going to argue against him) FTL is impossible, they'd have gotten here by magic (400 years, at least, just from Proxima Centauri - and it has no planets that we can find that could support life as we know it), so I'll return to reality, if you don't mind.

(Why is everyone suddenly so concerned about alien visitation without actually thinking about the fact that travel like that is science fiction, not reality? Stick to Star Trek - star exploration is going to be done by telescope for the foreseeable future. And probably for the unforeseeable future too.)

What is the science behind people following in love?

We call it love. It feels like love. But the most exhilarating of all human emotions is probably nature's beautiful way of keeping the human species alive and reproducing.With an irresistible cocktail of chemicals, our brain entices us to fall in love. We believe we're choosing a partner. But

Which is more likely; the existence of aliens or the existence of God?

This question is unanswerable.Let me start with the easy bit. The likelihood aliens exist is 100%. Let's use the Drake equation: N=(R*)(fP)(ne)(fL)(fi)(fc)(L)N is the number of civilizations we might someday contactR* is the rate at which stars are formed in our galaxyfP is the fraction of stars that are orbited by planetsfL is the

How could the space debris in Earth orbit be cleaned up?

I read a few answers that says we don't need to. If you say that to a NASA scientist, he might disagree with you. Yes, space debris are destined to come back on earth and burn in the atmosphere.But before doing so, they will orbit Earth for quite a while. And they might find
