Life is so abundant here on Earth that it actually gets quite crowded in many areas. I am not just talking about people but all life, from the microbes on up the ladder. So, how did life begin. The scientific world has a hard time answering that and the attempts to produce life in the lab has been futile up until recently and what they did come up with can't really be called living. They did create synthetic DNA which are the building blocks of all life. So, we must assume that creating a new form of life is very, very, very difficult. So why am I telling you about that? Just to let you understand just how lucky we are to be here on Earth and alive! And of course to explain why life anywhere else in the universe may be very hard to find or may not exist at all.
Our planet has been in orbit around the sun for about 4.6 billion years, give or take a couple of minutes (grin). It took a billion years for the first signs of life to appear, simple cells called prokaryotes. It took 2.6 billion years more for life to appear that was multicellular. That, my friends, is a long, long time. Then, 400 million years later, the first simple animals appeared. Anatomically modern man has only been around for less than 200,000 years.
So what does that have to do with wondering if we are alone? I just wanted to explain just how hard and complicated evolution is and that it can take many twists and turns along the way. So now, the scientist claim that there are 715 planets outside our solar system and that four of them are in its star's habitable zone. Therefore, there is a possibility that they may harbor life, but that life may be quite different than any we have known.
Another thing that makes me think that we are not alone is that the latest all sky survey had some unusual anomalies. Some scientists believe they were caused by the presence of other universes. Why should our universe be the only one? Remember my post on entangled pairs, maybe there could be such a thing as entangled universes??? Why is there just so many more questions than there are answers? One thing I know for sure, I want you all to have a great day, you hear?
