the way these sightings ignore the physics of our world makes me think we are living in an aquarium and they are beings poking their fingers on the outside glass.
This touches on another possibility - travel between dimensions. So far out there that our current laws of physics can't align with the idea.
Right and we don't and won't have the power to attain those speeds. We can only barely observe that speed/time connection in our extremely limited capabilities.
It doesn't matter. The alien probes don't travel anywhere close to the speed of light. Once they detect life on Earth one billion years ago, they know it will be hundreds of millions of years until something interesting happens. So they don't care if the fully automated probe gets here in ten years, or ten million years, or a hundred million years.
It’s a question power harnessing as time shrinks with speed provided you have the power to attain such speeds in the light of increasing mass.

But another civilization a million years ahead of us well might.

Yes, for automated probes, it doesn’t matter, but for them to visit us, they need to travel fast enough and to dilate time enough so as to make it within a fraction of their lifetime.
All the folks focusing on the enormity of time it would take don’t get relativity. Time isn’t an independent dimension or even real at all but a perceived one that slows down with speed. A photon feels no time and is effectively traveling at an infinite speed. Attaining near light speeds is a question of harnessing power, which a type-III civilization might well be able to do.
This is almost but not quite enlightened. Yes time isn't real, just an idea like relativity itself.
Where people still get confused is thinking the limits of this abstraction re light speed mean there's a limit in reality too. No! It only implies a limit in the model. The model tries to extend the inherently local concept of time to an intergalactic scale. This limit is strictly about how something non-local would be perceived from the local perspective.
So even accepting relativity as valid, what it boils down to is we have no concept of the time or speed of anything going faster than light. Can't be measured doesn't mean it can't be done.

People confidently declared that people would be killed if they travelled faster than a horse when the car was invented because they were certain the human body couldn't bear such speed.
Declaring with certainty to know things you can't possibly know is foolish.

They could extend their lifetime indefinitely. Or they could hibernate for the journey. Or they could upload their mind into computer memory and then 3D print a body once they arrive. Or ten other different ideas.
There are plenty of good reasons to doubt the ET testimony today. But "technologically impossible" is not one of them. We're talking about advanced aliens here.

Yup. Sort of like any speculation as to the existence or lack thereof of intelligent life elsewhere in the Universe. Fun perhaps. But all BS (except for the Bigfoot connection - that part is REAL).

Not really. The odds of there being no intelligent life on trillions of planets in a universe that's 26 billion years old are zero.

Gee thanks for informing us TheAdultinTheRoom. You are so wise and wonderful.

My point was we have no way of knowing. Perhaps the kid I was responding to who thinks he already knows the unknowable is the person you should be directing your "wise and wonderful" vitriol towards.

Sure, you could extend the unknown unknowns argument arbitrarily, but if they can indefinitely extend their lifetimes, then my claim above would simply not imply any lower bound on the necessary speeds.
But if they wish to reach us and get back home ever, our current knowledge of the universe’s physics would imply that they travel at least fast enough in both directions so that the intervening space that’s expanding faster than light doesn’t make that impossible.
I'm not religious. We can't get anything close to life in a lab. You need to learn more about the science of biology and chemistry. Dna alone is so complex it's probability happening again on another planet is not possible

I understand that you have zero understanding of mathematical concepts such as probabilities. That's ok, you can be a good person in other ways.

Maybe DNA first happened on another planet, then that planet got blasted apart, and rocks with DNA fragments spread all over the universe, and that's how life started on Earth, and that's how life starts on millions of planets.
Not really. The odds of there being no intelligent life on trillions of planets in a universe that's 26 billion years old are zero.
Let's say there will be 10^20 planets throughout the lifetime of the Universe. And let's say the probability of a planet evolving intelligent life is significantly higher than 1/10^20. Then your zero odds are pretty close. However, if that probability is significantly less than 1/10^20, then there's pretty close to zero chance that intelligent life forms anywhere else in the universe.
It's simple math. But, nobody knows what that probability is. It could be one in a million. It could be one in a trillion billion million. Nobody knows.
If you believe the US Government is all of a sudden revealing important information related to UFO's, you've got a cognitive deficit. Maybe pay attention to our "elected" officials giving hundreds of billions in taxpayer funded aid to "Ukraine" (US weapons manufacturers) and a continued effort to influence media from the White House down.
