Humans will have a close encounter with aliens in the next few years.
NASA’s former chief scientist Jim Green is convinced that extraterrestrial life exists and thinks it is only a matter of time before they will be found by the human race.
He said: “I think we are going to see some really astounding discoveries in the next handful of years.”
Green revealed that he expects alien life to be found within his lifetime.
He explained: “We are making enormous progress. Now we know there are more planets in our galaxy than there are stars.
“And many of them are in places much like the Earth, where we can receive the light from the Sun and we can have water. These are important conditions we believe for life.
“We are finding planets that have conditions where life may arise.”
