I dont need faster than light travel, I just have to have developed earlier than you.
You know what a Von Newman probe is?
Its a machine that is capable of self replication.
So lets say that thousands of years ago an alien species identifies solar systems with planets inside their habitable zones and launches Von Newman probes at them - no faster than light travel required.
Also explains crashes, the mini-probes, built by the "mothership" are literally that - expendable.
We are literally talking about doing something similar to Alpha Centurai
Im not who replied to, so no, I didnt suggest that.
And then you contridict yourself by pointing out other options that exist beyond FTL travel.
Another example: Von Newman probes? There could easily be something in the solar system that was sent eons ago to solar systems with habitable planets that reports home occasionally.
Would also explain crashes, the expendable probes are made to be just that. Expendable.
Just today we had a comet that was detected until right before it was on top of us.
You are wrong. We have never had basing options or launched attqcks from Israel.
Also, getting military overflight from them is a huge pain in the ass and theyre always dicks about it.
