How would one define a life form?
If you had to look at all the conventional parameters, it would be an organism that is present on Terra Firma or somehow tethered to it, breathes in oxygen in some form or another and has to consume some sort of food stuff to be able to sustain it and to allow it to procreate.
And it has been created by a super entity, which for the avoidance of any religious arguments; I refrain from giving a name.
So to simplify, the organism needs a medium in which to exist, substance to provide it with energy and a means by which it can reproduce.
Some of the organisms are benevolent, some are symbiotic and some are destructive. All in all the balance between them is quite equal so that if left alone all of the species survive.
This applies for the largest to the smallest organisms found on this planet we call home.
But what about us humans; have we ever created a life form? To my mind the only one I can think of is the computer virus. As a life form is conforms to some of the parameters. It is present on Terra Firma, but in reality is not required to be tethered to it. It does not breathe oxygen and it does not need food to grow or reproduce.
And it is destructive. That is the sad part. The only form of life that we Homo sapiens have produced and it is destructive. That is a very sad point.
What does it say about us?
