Aliens :- organisms from outer planets are called aliens (extraterrestrial) .
You may have been knowing about aliens . Many of the people don't know about them or some people don't believe it . But they are really there .
From the ancient cave paintings we know that they have came to earth many many years ago . There are the figures of spaceship and some extraordinary creatures in those cave paintings .
Another clue is also there . There were devices made by scientists to detect strange signals . In 19th century , I don't know exact day but a signal was detected . The signal was 'WOW'. It has came from outer space.
People say that one alien has seen our earth and he found it very beautiful and said ''wow".
There are also several myths related to aliens .
I will publish those myths to you in another part .
