When aliens came on earth!
When aliens came on earth after a million years from present time!
Alien 1: We have reached to this planet. Do you know its history?
Alien 2: No.
1: Ok!. It was once dominated by two legged animal species known as humans. First they cut all the trees on their planet, constructed concrete structures all over earth, increased their population multiple times, polluted their planet and depleted all the resources of their planet. So, their planet become too hot to live. Then they capture all the carbon di-oxide from their environment and freezed it and dig the containers deep down on earth. They also created an artificial cover over the sky to stop Sunrays coming to the earth.
2: OK then?
1:Then the Sunrays couldn't reach to earth and there wasn't enough carbon dioxide in the atmosphere. So, their planet soon starting freezing. They all died of freezing temperature. Lol!
2: Oh! They were freaking deepheads!
Lolz!
Actually sometimes I usually imagine how the world will be if alien start living with us. Or probably they have started living with us and we are not really aware. Well probably time will tell
Yeah. Till then everything is speculation. We can imagine but actual may be very different from it.
