I don’t think it’s that crazy.
What’s crazy is thinking eggs are bad for you and that the fabric of reality itself is nothing but a social construct
(I do recommend the Illuminatus! Trilogy from Wilson and Shea, for interesting alternative history fantasy and all kinds of crazy stuff)
If we can find the Titanic we should be able to find the Atlanteans. Maybe.
And that lost civilisations existed, I have no doubt.
But likely not with laser tech.
Not really. Just look at abandoned places today, and you can see how quickly nature takes them over and erases them. Sometimes traces can be found, like ancient cities that are sometimes found in the jungle of central America, but that's after ~500 years or less. On much longer timescales, nature and geology bury or destroy most evidence. If you're really lucky, something might be dug up, but that's rare. The only reason so many prehistoric fossils (dinosaurs etc) have been found is because there are SO many of them: they existed for hundreds of millions of years, all over the planet, so we've captured a tiny slice of what lies beneath the surface.
Perhaps there's some evidence of a past advanced civilization buried somewhere, but we haven't found it yet.
The Titanic is barely over 100 years old, so of course it's (partially) still there.
I admit I went too far with the lasers but my thinking is that the fact that we are alone in the universe gives a lot of credence to the theory that we live in a simulation, and wouldn’t “Age of Atlantis” be a fun mod?
We’re still hunting dinosaurs. Wild Turkey season opens pretty soon where I am.
