    Whynisnit always assumed that life elseware has to be anything like ours or signs, typical human arrogance and ignorance. If you were an alien.would you wanna know us, and who's to say they would want a talk to us they may wanna talk to other creatures on earth, the earth, needs a new hard reset, to wipe ut the scum of the earth, which would prob mean most of the humans. If I was a an alien I would want to wipe out humanity, due to many people being scumbags.

    Likely Ouamoumo is /was a space probe if not a spacecraft, 🛠 hmmmm…?….. maybe a 😴 sleeper 😴 spaceship just passing through ?? A Battlestar Galatica deal going on,? Lol. A civilization of people, alien beings in deep sleep stasis, only to awaken when a suitable world/ s galaxy ideal for the beings inside are determined by ship,s computerized A.I. internal tech systems. Nice, interesting fun concept to think of & imagine & speculate, who knows? Not this time, maybe the next will be so? Keep watching the skies,Lol.Maybe? 😮😊.

    He’s making a false assumption that technological inferiority means a military won’t stand a chance.

    This is a fallacy.

    Inferior military tech can still win.

    Why would they need to build bombs 💣 if they could use meteors and comets 💫 just redirect them into the earth ! You may have to wait out a nuclear winter after all the debris and volcanoes 🌋 and earthquakes!?? Wait it all out a few years , then swoop in with people reduced to hunting and gathering! We'd be so weakened , if they want a slave race here we are ! Man that's scary ! N like I said that's if they don't need to terraform the earth fir there needs to be! We're screwed if they aint nice !

    this is an statement froma believer : all the extinction event are more morbit then you can imagine ..but the funny thing is the common thing is every earth ending event is written in the book of revelation.
    I challenge you to read it if you're interested , because this is how i have started my Faith journey.
    The Truth is : noone can escape God's Jugdements on a Christ Rejecting World.
    Use common sense and ask yourself : W H A T I F ? GOD IS REAL ? and JESUS IS WILLING TO SAVE YOU ?
    This is a challenge that goes above every human understanding So please choose this day on where you yield your knowledge to

    to be honnest there are no aliens an attacking us for resources is pointless
    Because many astroids are full of rare earth minerals such as iridium and dimonds and so on.
    Becides the aliens that we or our imagination have created these beings , but in reality , theese are fllen hosts that have rebelled against God.
    I'm a,azed at your level of speculation but only as a source of entertainment.
    Just cooment back if you are interested in God's Plan for humanity , but only if i have poured enough salt to make you thirsty for the Truth.
    I have remembered many of your video's and in some of them we are offspring of a few millions of Years back that we were reptillians once.
    THIS IS AN INSULT OF US ……Being created after GOD's Image but we have failed the Test and opne came down To earth To Get Things Right.
    But seriously sinds my flesh craves entertainment i need to be vigilant as well .
    Because many scientific theories can cause out Hearts to drift away from our Creator who creat4ed Earth after the earth darkness and light over the Earth after that i big light for the day THE SUN and at night THE MOON AND THE STARS. not the other way around.
    But i grab my popcorn and enjoy your show anyway
