and if there was water there does it mean we're going to leave the earth?
as far as i know, utter space is full of toxic gaz, so in order to live there we will have to wear masks---POINT 1 GAS
there's no gravity there, so how are we supposed to start civilization there, we will have to use maybe 10 times of iron and concrete to stabalize the building there --- POINT 2 GRAVITY
traviling to the moon or out of the earth costs ALOT, and this cost will INCREASE with time, because rockets works in FUEL, and as time goes by the FUEL is expiring, so even if many travel agencies spread and started making trips to the moon, by the time this happen the fuel will be more expensive than now (if not expired) --- POINT 3 COST
i know many people on earth, and i don't wanna go and live alone (or) with other people, i wanna stay close to my friends, i can't even garantee communication from the moon to the earth, and if there was a way to communicate earth it will be either COSTY or with bad quality or earth people don't have /can't afford that technology to receive my communication ---POINT 4 I LOVE EARTH
that's more than enough reasons for me...
