Some questions re: life in rural Arizona?

Life on other planets theories and questions? (In details)?

• I have been thinking about "Life on other planets" I'm 15 so I'm not the most "Experienced" with this subject so go easy if I'm crazy lol But 1 Idea I was thinking is that there may be a possibility that there is no other life out there that is like us (Not to be taken as there is no life out there period). Because our ability to create, use tools, and communication is our nature and instinct. You take a look at other animals on OUR planet, and some of them may share certain traits, and instincts but NONE of them have it all packaged into one like us and as advanced as ours. So what if we're the ONLY type of our kind? What if we're the result of a very rare chance. Because in order for a intelligent species to "Thrive" like us. They need the intelligence and understanding of Cause and Effect, Curiosity, and VERY advance problem solving skills, then they need the limbs and the full range ability (Such as arms, hands etc etc) and the ability to even use tools, Then they need the MOST IMPORTANT of all an advanced form of communication. They would almost have to be or at least be very SIMILAR to Humans or Monkeys. Now I know that the Universe is VAST but but we might be the only life of our kind. or for a LONG ways anyway. and then you have the possibility of Life somewhere else being unimaginably different. Then I know this idea is pretty far fetched, But what if life on Earth is the result of some other intelligent being (Possibly other humans) found this planet and sent us here some how? What if instead of them coming here what if they froze and sent cells here so they could survive the long journey or something here to fire up life on Earth instead of sending themselves. For maybe the survival of the species? I know there is a lot of things that need to be taken into consideration such as evolution and such. But still what if it is a possibility. We talk about ways to terraform ( I know that's probably spelled wrong) Mars and do such things because think if we were to terraform a planet (Or send life to it) We would send MANY species other than just... Us. so what if we are a result of someone actually doing that in a smaller way? I don't know just some ideas My brain isn't all with me, So if I used some terms that may not make sense understand lol

• Answer:

  You have to ask yourself, what do you define as living. Perhaps, living is a different concept in other worlds, and what we perceive as non-living, is actually living in other element-based lifeforms, not just carbon-based lifeforms. Taking the Drake Equation, approximately 800 planets have living life forms right now at this moment in our galaxy. As for your second question, there is no answer, as no one has fathomed that. It is definitely possible, however, geologcail evidence, creation of the Earth and the evolution of life somehow tells me different.
