About aliens:
'The universe is so huge, for life only on the Earth, that would be total waste of space'I don't think the Earth could be THE ONLY place where is possible life,
there is huge chance that anywhere in whole universe could be similar living conditions
I heard lot of thoeries, but this one seems intresting for me:
Someone said, "Why Aliens? Do they have to be 'alien'?"
His theory is, maybe bit complicated but, very intresting,
he bets that UFO are humans from future, visiting the past.Have you ever seen movie 'Terminator'?
There is the idea (I know this sounds like total sci-fi, but hell)
Couldn't human from future, who have very bad living conditions try to send someone to past, so he could change their fate. Why not?
Another thing:
Why aliens could visit the Earth?
Someone says they are visiting us regulary, because we have 1 of the most important matery in the universe, water.
There are loads of diffrent, very intresting (or just stupid) theories, so...
Back to topic...
Intresting one:
In few ancient nations there was know idea of
VimanaIn theory, acnient flying machine.
A vimana is a mythological flying machine, described in the ancient mythology of India. References to these flying machines are commonplace in ancient Indian texts, even describing their use in warfare. As well as being able to fly within Earth's atmosphere, vimanas were also said to be able to travel into space and travel submerged underwater.
