I wish I could find the video of some scientist doing the math of the Drake equation and essentially even being super conservative with the numbers being plugged in, it still came up with something between 1 and 100 million advanced civilizations throughout the universe. I fully believe there is advanced life out there just for the math.
We haven't been visited. We just aren't that interesting and on a cosmic timescale, we are still in the nursery. Why would they come here when there would almost assuredly a similar civilization somewhere closer to where they are located?
I'm old enough to remember when exoplanets were still just a theory (and I'm a huge space nerd and have been since I was a very small child) and then we found the first one in the mid 90s. Since then we've found thousands, some inhabitable for life as we know it, others borderline, and some look promising for life. I really believe with expeditions to Europa, Io, etc. in the coming years, we are going to find evidence of life or life itself essentially in our backyard. That would, in my mind, make the odds of having advanced life throughout the universe rise.

Even if we could match the speed of light, aren't some galaxies essentially like 400 years away? The closest galaxy to ours is Canis Major, a dwarf galaxy that orbits our own. At light speed it would take 25,000 years to get there. But aren't you essentially travelling through time at that point? Even with the speed of light, anywhere that would be close enough to travel to within one human life we can see in a telescope. The theoretical "warp" drive actually compresses spacetime, so you're not actually moving faster than light but rather making the distance between you and your destination shorter. It is, essentially, the "poking a pencil through a folded sheet of paper" trope. Physicist Miguel Alcubierre's theoretical drive achieves this without violating the known laws of physics, but – as mentioned in my other post – there is no possible way to power it at our present technological level, beyond the impossible brute force method of converting all the matter in the universe to do it. There's nothing to say that ways of generating the power required won't be found in the future, however. So if we ever got it to work, warp travel could conceivably enable a human spacecraft to travel to another star and back in a relatively short time with none of the time dilation concerns.There is so much about space I don't understand

There is so much about space I don't understand It can be pretty difficult to wrap your head around. When we look at a star in the night sky we're looking at the star as it was however long it took the light to travel from it to your eyes. So, if you're looking at a star 400 light years away, you're looking at that star as it was 400 years ago. If we could travel at the speed of light it would take the ship 400 years to get there. The catch is that the faster an object travels the slower time moves (a good example of this is GPS satellites, which move so fast that they have to be frequently re-synced with computers on Earth because time moves fractionally slower for them), so while on that ship 400 years will pass thousands of years will pass on Earth. This is the premise of the original Planet of the Apes movie, BTW. In theory, a warp drive could "fold" the space between that star and Earth, so that same 400 year trip could take significantly less time, and because the ship could make the trip without accelerating to ridiculous speeds there would be no time differences. The added bonus would be that in 400 years anybody pointing a radio telescope at that star would detect the ship arriving.

I believe they've visited us. So no judgement from me, my dog. I think he was disagreeing more with my reasons for why I think aliens don't contact us. Just because I disagree with you or say something in a manner you find objectionable, doesn't make it unsafe. Did I doxx you? Did I encourage others to mock you or shun you? No. None of that. This is the sorry, not sorry, part of life where you may find other humans aren't willing to just agree with you for the sake of harmony.

We were supposed to have flying cars and green skinned mistresses by now Blame doc Brown for that, something he did post delorean f***ed up the timeline

If aliens visited us, they would want to talk to whales, not us.
Star Trek IV was right.

They exist to me, just based on probability. But the universe is so vast that I have grave doubt we'll ever encounter any.

Aliens I believe do visit us, but we could be off limits for first contact due to our warring nature. Why do people think aliens would be any different from us when it comes to war? So much science fiction has made us believe that other planets and species would be completely homogenous, when it’s incredibly likely different parts of a planet would create life that is as diverse as we have on earth. With that diversity, they’d probably have the same conflicts we have on earth. As for earth being visited, I’m not sure. Based on how big the universe is, there are most likely some species that can travel long distances. For others, it’s probably not possible because of the cost, energy and time it would take.

Ya'll know the first message we get from aliens will be "We've been trying to reach you concerning your planet's extended warranty. You should've received a notice in the spacemail about your planet's extended warranty eligibility. Since we've not gotten a response, we're giving you a final courtesy call before we close out your existence."

Hell, look who's pushing space here on earth, hardly the most enlightened of the species, we could end up with space Musk all over us.
