Is there anyone out there in vast space?”?
Traces of life on Earth has been discovered so far back in time that there is now only a very short interval between when the Earth became slightly hospitable (liquid water on the surface) and these first traces. Given the complexity of even the simplest living organism, to me this suggests that life probably arrived on Earth from outer space, in the form of some kind of space-hardy spore. The actual evolution of life could have taken place over a much longer period somewhere else in the galaxy – our solar system is “second generation”, only around 5 billion years old, whereas our galaxy, the Milky Way, is around 13 billion years old. If true, this suggests that life as we know it (ie with the same basic chemistry) probably exists everywhere in the galaxy that there is a suitable physical environment, having drifted around (in the same was as pollen and fungal spores do on Earth) to every corner of the galaxy from one, or perhaps a number, of original starting points. Life evolves, so
Yes I do believe we are not alone. Let’s talk about our Galaxy the Milky Way. The Milky Way from one end to the other is about 150,000 light years across! consisting of 200 billion suns! Our sun is a minute speck in one of the spirals. Now lets look at Galaxies, there are millions of them in space each one of those consisting of billions of stars. The likely hood of no life in space is very minute. Our own galaxy is so big we can’t even travel anywhere other then the moon or Mars. The thing to remember is just because we supposedly haven’t found it doesn’t mean it does not exist. It has been proved that there are more stars in space then there are grains of sand on every beach around the world 10 times over! They are out there but where no one that I know of knows! However a signal was reported to have being heard back in 1977 at S.E.T.I that came from space! To this day it has never being explained what that signal was, but it was from far away in space!
