Musk: I haven't seen any evidence of aliens yet. I'll tweet as soon as I find out.

CTOnews.com, April 20 (Xinhua)-- Space X CEO Elon Musk is a well-known space explorer, but he says he has not seen any evidence of conscious alien life anywhere, at least not yet.

"A lot of people ask me, do you know where the aliens are? I think I'm probably the one most likely to know if there are aliens on Earth, "Musk said in an interview with the Tucker Carlson Tonight Show on Tuesday." Yes, I'm familiar with space. But I don't see any evidence of aliens. So I hope-- if I find an alien, I will tweet immediately, which may be the hottest tweet in history. We found one (alien), guys! " He said jokingly.

Musk recalled hearing a story about a general in the 1960s who wanted to expand America's defense budget and came up with the idea that if aliens were found, they should be announced immediately.

"do you know what would make everyone not object to an increase in the defense budget? if we claim to have found an alien,'we need money to protect ourselves from these guys.'" Musk jokingly explained, "so the fastest way to increase the defense budget is to find an alien." Musk also said he did not believe that the government was hiding the existence of aliens from the public, and that if the government knew about the existence of aliens, they would publish it so that military spending could be easily approved.

Musk added that as far as he knows, there is no evidence of "conscious" life in space, but if so, he wants them to be "peaceful".

Musk also shared his concerns about the decline in the birth rate, saying that he wanted to see civilization "move forward" rather than go to the low end of population rebirth. "I am worried about the decline in the birth rate, for example," Musk said. Japan killed twice as many people as it was born last year. " Mr Musk also warned last month that Italy would become "unmanned" after it became one of the lowest birth rates in the world, CTOnews.com noted.
