Aliens on Earth?

[oscsr]

the issue about aliens is so speculative and the most perplexing one.it is difficult to scold those pilot claim to see alien aircraft on the course of their duty and the government on the other side alleging there is no alien or other creature on earth or outside our universe. what is to be noted here is just the calculation of probability. there are billions of galaxies out in the universe with billions of stars in it and this billions of stars are believed to contain at least a planet. in the eyes of reasonable man anticipating at least one of the planet in might contain life even in microbiology form is acceptable to.when we talk of aliens what comes first in our mind is just human like creature or those creepy creature we watch on movies that is why we refuse to believe that especially religious people. such conceptions shall be rectified because aliens means any creature including life in microorganism form and as far as am concerned i believe there is life in such form out there.
.aliens on earth? the speculation is dependent on whether the human has entirely watched and mapped each and every piece of the planet. the answer is no. most places like forests and deserts are free from the eyes of mans so who the hells know that there is a creature that is not still known to man.i.e aliens.? do not forget that though it is difficult to produce a material evidence there is still a probability.
