Everything is... Yes, even rocks. Because they have carbon, and carbon gets reused ( the carbon cycle ) . Therefore, everything on this earth has carbon, which means everything on this earth is alive. Yeah. I'm in 6th grade.
I am assuming you mean sentient (can think for themselves, such as humans or cats, not like lamps) then of course the answer is no. How else do you classify "alive" ? Oxygen is also abiotic which by definition means it is not alive.
actually I did a little research and have come up with it is NOT in fact alive, carbon is NOT alive just because it evolves does not mean its 'alive' it means it is a working substance that when times change it evolves, so it's not classified in ANY science as 'alive' but if you are stubborn and want to think the 'single cell organisms' are alive I don't care (but there are not).
No there are ( characteristics of life) that said thing needs to be considered "alive" oxygen cannot evolve (1.) it cannot grow and/or develop (2.) if said thing does not meet all five characteristics ( 1. Capable of reproduction 2. Growth and development 3. Evolution 4. Being able to adapt to your environment 5. Made of cells) it's not alive
