Certainly are the evidences of Aliens!
They have been visiting Earth since decades;
Perhaps they would be knowing us since long
And it’s time Earthlings should over take them!
As Stephen Hawking says they could use our planet
For the sake of utilising Solar energy for space venture;
Man would be a dwarf before the giants then here!
Computers and micro chips are inventions due to them
And space shuttles are too developed due to them;
Otherwise we would not have waded through superstition!
Now man has to save Earth against pollution and Aliens
By updating technology for advancement for good only!
