Aliens

In the news this week are reports of alien ship parts on earth. The have been around for a couple of decades but the government has kept it secret. A scientist will tell you that these reports are not believable. Our nearest star is alpha centauri has an earth size planet called proxima b and it is located in an orbit that would allow for liquid water to form. This suggest the possibility of life. Since alpha centauri is 4.37 light years away a ship traveling at 1 million miles per hour would take 30,000 years to get there. If the centaruians had the capability to get here they would certain have radio and those radio transmissions would reach earth in 4.37 years and the US has been looking for radio ways from space for many years and none have been heard. The earth has been sending out radio waves for many years and the first waves have traveled 130 light years. If anyone picked up on them and decided to answer that would mean stars within 65 light years allowing for time out and time back. There are about 2,500 stars within that radius and no messages have been received. As much as I would like to believe in alien civilizations my math tells me they have not been here.
