Could they be like us? I never allow myself to ponder this subject, from the outside this question sounds almost dismissive of the subject matter, "How much like us are they?" See with Extraterrestrial life, We have questioned every angle we can think of and postulated every outcome for visitation from unending world peace to pathogen outbreaks that end all life on earth. But, There is the Idea of panspermia, That life was seeded here that the true origins of life are from somewhere else and it landed here on meteors and comets, and those simple life forms, Began to evolve and adapt to this planet and eventually they evolved into what we are now. So, my question is this, Could we share a common ancestor with an extraterrestrial life form? Is life something that spreads through the universe like panspermia? or does it just form when conditions are fitting? Many believe that mankind may have been genetically altered by some outside intelligence, We really don't know why Human beings are so advantaged over other life forms on earth in the ways that we are, Firstly, While we don't have the largest brains of all life forms on earth, The blue whales brain is actually a bit larger than a humans, And the Dolphins brain is just amazing to study, I'd suggest it " Dolphin Brain and Intelligence "if you are interested in that kind of thing." The thing is, our body to brain ratio is amazing, Our brain accounts for 20 percent of our overall energy output, That's 1/5th of our total energy haul, more than any other organ in our bodies, That's quite unlike most other life forms on earth. There is no mistaking it really, We humans are seemingly unique among other life forms, We are so unique, We seek a kinship, We seek to find something anything like us. We ask, Are we alone in the universe, But the true irony is, We search because we are alone, Looking to find something, That is anything like us. So, My question is, The universe is seemingly quite vast, Life May share a common origin in the cosmos, What are the odds, in this vast universe, Of there being, Not just a planet of intelligent life out there? But something almost exactly like us? in almost every way. Ultimately, How Unique are we really in this cosmic landscape?
