The presence of ghosts is only as close as your belief.
The existence of aliens is only as far as your rejection.

I don't believe that aliens exist, but I do believe that any new facts can strengthen foundation of my belief.

There are people who really believe in and fear of ghost. Some of them even are too afraid that cause their minds and senses are no longer function properly to be able to distinguish whether something is ghost or else.

There are beings which exist outside the human eyes' visible light spectrum. They are only a fraction of the invisible hard evidence of the aliens existence.

Some people believe that human is a native people of the planet earth, others believe in the opposite. I believe there is a part of me that originated from planet earth, and the rest from elsewhere.
