How long can aliens live for?

Answer 1

The evidence is strong they have a longer lifespan than normal humans- unconfirmed reports of an autopsy on a dead female ( UFOTRIX) in Russia, this happened in l996, led researchers to believe she came from a planet 200 light years from Earth/and the design of her brain suggested she came into being in earth year l796. So her planet had space travel in the time of Catherine the Great! Naturally deceased Lady Alien was nicknamed Catherine. it is sad there is not more international co-operation on cases of this sort.

Answer 2

Aliens have been visiting earth ever since we started building. I mean from Easter Island to the Pyramids. They have shown up everywhere, they were in The Bible, the Aztec calender, the Mayan calender, and the ancient Egyptian Rye scrolls (the story of all their gods/aliens leaders). To really answer your question, about since 30,000 B.C.

Answer 3

Some Russian evidence hints at 200 plus years- or that they had space travel in the period of Catherine II, who died in l796.
