Bomb the shit out of them

No one would care. If they are here they have been here for a long time. Not to bad so far.

The article doesn't talk about aliens turning up on our door step but us spotting their signal from many light years away.
How would humanity reacts to such evidence? Some would be inspired, some would deny it, some would think about it only briefly before getting distracted by the next celebrity drama.

Stay friendly, they might be more then millions of years ahead of us...

I'd put up my thumb,I want off this ferigie world that turns on profitt

They would be rounded up for scientific study

That is a pretty large assumption, that we could find aliens. We've only gotten five things out of the solar system so far at immense cost and none of those are remotely close to anything else anything could live on, even after traveling through space since 1977. There's also a question of how detectable other species would be. Most species on earth haven't the insane urges humans have to destroy the planet they are living on through "progress", instead, they live in equilibrium with their environment, perhaps realizing they are already on a space ship. But if it did happen, one can be sure there would be an effort made to destroy the aliens in order for a few to make a profit. That's how we roll.

Steven Hawkins , I believe , said we're all made of star dust . We are the aliens .

Yeah, probably act like spoiled two four year olds and act the fool

Kill em, shag em n eat em.We have form...where are all the neanderthals?

Some folks... a small percentage; would freak/fritz... I suspect the overall effect on humanity would be positive. An opportunity to realize they're not so all important.

We would first bomb them then rebuild their cities and try to build a nation state like ours and fail.

I would put my money on full tilt expression of paranoia and aggression
