Good argument. However, while bacteria may be a form of life, are they they source of life itself? I've studied biology and chemistry, and am fully aware as to how they functure and how many are out there. But what is the difference between Life and Being Alive?
The flower that opens it's petals to the sun's warm rays is alive. The horse that bends its neck to champ on the grass is alive. The child that draws a painting of it's parents is alive.
While single cell organisms are a form of life, I don't think they are "Alive" in the same sense as these other beings. If they were, the human body would be nothing more than a "town" of these cells merely working together. And yet, that's what we are... a bundle of cells that are working together for a common goal.
And yet... that isn't what we are. Not just what we are. There is something else that binds gives this mass of cells and tissues a thought, a voice, a identity. As well as these others beings. There's something about this life force that makes these "bundles of cells" trully alive. Those cells, bacteria, ect. might be what we're made of, but I don't believe that that's just simply what we are.That goes for any living creature.
Something, I don't know what it is, but something forms this "Life". This awareness and the different levels of it that all living things posses.
These are just my beliefs. But what do I know? I'm just a young, naieve idealistic philosopher.

But sometimes I think we're to logical and too scientific about things. When I look at a cloud formation, do I really need to know that it's formed of water vapor, composed of H20, and it's shape is affected by yadda air temperature and yadda air pressure? Or do I simply need to know that's its beautiful, intriguing, and natural.
Sadly, I think the more our race have tried to understand nature and our world, the more we've grown away from it. At one point, we went from understanding how it works to merely knowing a bunch of facts and figures that don't come into our lives very often. Therefor, we dismiss and ignore those facts.
Here's something I've wanted to ask a few people. The Sun is a massive sphere of increadibly hot plasma. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium.
That is what the Sun is. But is that
all that is is?
