Most humans need mystic or religious experiences in their lives.
Rejection of orthodox religions and old religious practices leads many
to look for replacements. Some choose harmless variants on old themes or
develop other New Age mystic practices. Science itself is seen by some to
replace the need for religion, for others it is elevated into mysticism.
Aliens can be seen as personifications of science and the ultimate in
'Other Worldliness'.
In 1968 Von Däniken claimed, in his book Chariots of
the Gods? (which was later made into a documentary) that the gods of old
civilisations were in fact alien visitors, who had built the great monuments
of these civilisations - Stonehenge, the pyramids etc. Perhaps there were
no gods, just supremely powerful aliens.
For many, support groups for
'survivors of alien abduction' have become the means to 'spiritual growth'.
Others have developed religious cults based on ideas developed from the
myth of the Alien and UFOs.
A number of cults have taken these ideas to
extreme.
Some could be harmless. Others lead to terrible disaster.
Heaven's Gate religious group was one such. It began in the early 1970s -
as did a number of others but in 1997 the current group members, and some
former members committed suicide. Thirty eight members and the leader were
found dead in their 'community' in California. They believed that the Earth
was about to be recycled and that they would be elevated to a higher plane
by aliens.
