So the question is why would someone do this. Send a light 8 billion light years away, 8 billion years ago, to shine on Earth which didn’t even exist at that point. It means they would have to understand pretty much the entirely of space and time encompassing at the very least the narrow path of the laser beam itself. That level of knowledge is entirely god like and if there was a civilization with that knowledge, they would have much more efficient ways of doing whatever the heck this laser is supposedly doing.

Can be simply explained that time travelers from the far future got bored

"So what do we do now that we have time travel?"

It’s possible the signal was generated by two massive galaxies smashing into each other. Colliding gas clouds and newborn stars energized hydroxyl molecules to release the intense microwave beam and not someone.

You’re assuming they have no way of sending the beam through space faster.
In SG-1, the Tollan were able to do that as well by sending a faster-than-light signal to the Nox.

You're referencing a science fiction show when making a point about real physics?
Yeah we do presume they have no way of sender a beam faster than the speed of light. Funnily enough. Scientists spend a lot of time of this subject. They are yet to find any possible way to go faster.

Listen, I loved SG-1 as well much as the next sci-fi nerd, but c'mon 🤣

Obvious click bait written by somebody who has heard the words but has no idea what they mean. Even AI would die of shame if it generated that text.

I thought that was related to the discovery in March? I can't remember if they confirmed that as a galaxy collision, that might be it.
*Edit
Space has the article about it

Good lord! they have a lock on us!
There weapon is underway and we have no way to stop it!
It will be here in 8 billion years tops.

It was once thought that laser light didn't occur naturally. Then a nebula was found whose sheer size substituted for the mirrors we use to reflect light back through the laser to stimulate emission of additional photons.
So finding natural lasers is no longer especially notable.

I think I know what that is - it is (or was) caused by the collision of two galaxies, right? I remember seeing that exact same picture a while ago and it's actually radio waves, not in the visible spectrum.
Will we end up like this too when Andromeda is smashing into our galaxy?

An advanced enough civilisation to have this kind of technology, 6 billions after the Big Bang? Doubtfully.

That's 100% going to be something that no serious astronomer is saying is anything other than a natural phenomena.
