Primitive Alien Life May Exist!

Are there any aliens? Is there any life in the other planets? Do we live alone in our galaxy? all of these are very important questions that always have confuse all of us and many astronaumer and scientists.
Now, Stephen Hawking, has come to that Primitive Alien Life May Exist.

Given thesize of the universe, it is unlikely that Earth is the only planet to develop somesort of life, Hawking told an audience at George Washington University inWashington, D.C. He added that humanity must embrace space exploration, if onlyto ensure itslong-term survival.

Theprobability of primitivelife developing on a suitable planet may be extremely low, or it may behigh, but aliens intelligent enough to beam signals into space may also besmart enough to build civilization-destroying weapons like nuclear bombs, hesaid. More likely, he added, is that primitive life is likely to develop, butintelligent life as we know it is exceedingly rare.
Hawking concluded that "If thehuman race is to continue for another million years we will have to boldly gowhere no one has gone before,"
