So I'm an astronomer by heart not by education I teach my self astronomy and go outside on a no moon clear night because you can see the stars more clear. I also focus on the climate as well because the better the climate the more bright the stars will be so when I look at the sky it's the only time to get a glimpse of outer space since earth is another object in space I made a philosophy stating we basically are in outer space. Though let's get down to this thing do you believe in Area 51 and Aliens or aliens in general? Some people around my area don't have that thing for astronomy so they have no clue if extraterrestrials are real any way do you believe either way yes or no? It's cool if you don't but with all the observable galaxies and exoplanets I highly doubt we're alone.
So let's get down to the evidence it's clear that it isn't IMPOSSIBLE to make underground bases that would be like saying it's impossible for navy ships to exist. I can also tell you they use a lot of security to detect if someones trying to infiltrate the base so it would be pretty hard unless you're smart not giving anyone ideas and I'm not held responsible. Any way if they are real and exist in Area 51 shouldn't we just respect what their doing and leave it alone unless they're holding aliens captive.
