Interesting topic @josefpius
I had those kind of thoughts several times and I found them just to scary and pointless. So I decided to focus on what is in front of me.
To make my life better and to make life of few people I care about better as well.
I like to think of UFO, other universes, virtual reality, AI etc. And sometimes Im not sure if I even exist but then I always snap out of it and focus on what's important: life in front of me.
At the end of the day those kind of thoughts are dangerous.
