We are here; we exist and we have the right to exist. Even non-sentient beings like flowers have the right to exist. If negative force is exerted against them, then, on a chemical level, flowers repair themselves to survive. But more than that, we human beings including insects, even amoebas, the smallest beings are considered sentient beings. And as sentient beings, we have even more mechanisms to help us survive.
Things that can move under their own will or desire, that’s what a “sentient being” means, according to the discussions that I’ve had with scientists. “Sentient” doesn’t necessarily mean being conscious or being human on a conscious level. Actually it’s difficult to define what “consciousness” or “conscious” means. Usually it means the clearest aspect of the mind, but then, is it that there is no consciousness when we are semiconscious or unconscious? Do insects have it? Maybe it’s better to speak of “cognitive faculty” rather than consciousness.
