Hello PF. I will give you my thoughts about the chance of there being life in the universe and I would like you too write what you think and maybe come with arguments against me. I am not very pro in any way at all so I may be incorrect in some things and if I am I would be happy if you can correct me. Most of this knowledge I have learned come from Neil deGrasse Tyson I should say and I share his beliefs. I should say I talk about intelligent life and my definition of intelligent life in this thread is the knowledge too send radio waves, communicate and send objects into space. Our atoms are made of hydrogen,oxygen,nitrogen and carbon. Our body is 60 percent water = H2O = 2 H atoms and 1 O atom our DNA is based on Carbon and Nitrogen occurs in all living organisms we know. If we look at the most common atoms in the universe we find the exact same atoms; hydrogen,oxygen,nitrogen and carbon. We know, because of modern astrophysics, how those atoms are made they are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars exploded, what we would call a supernova i guess, scattering their atoms across the galaxy. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems stars with orbiting planets. And those planets now have the ingredients for life itself. IMHO the universe is too vast, there is way too many stars, way too many planets throughout the universe with those ingredients for life itself, that life would not drive of one of those planets would be very ego too suggest. One could argument that, yes we haven't found life yet but IMO that argument is not really valid when we consider how big the universe is contra how much we have looked. In my very humble opinion life is just an invertible consequence of complex chemistry. Now; Do you agree with me or do you think I am completely wrong? /WeW/ By the way sorry for my bad English but I am from Denmark and don't get too write or talk English that much.
