What is Life ??

Our existence as a physical being starts at the moment of conception, when the nucleus of a sperm merges with that of an ovum, and a new DNA-pattern is formed. To put it very simply, the DNA in the cells merges into a new combination of molecules, which then splits in two separate halves. Both parts accumulate new material and, in the process of cell division, they grow back into an entire nucleus, and now now there are to cells. Then the whole process is repeated, again and again, forming new cells from 'raw' material. The building blocks are very complex, and we do not yet understand all the chemistry involved. But if we look at it this way, conception and growth of a human being is just an enormously complex chemical reaction, of which we are the end product. This reaction goes on and on, until we die. Then the body decomposes, and the chemicals bonded in it are released to be used again as raw material for other, similar reactions. In other words, at the physical level we are nothing more than a very complex chemical reaction.

There u have it. One of the biggest questions in life, has now been answered.

You have totally overlooked a very important aspect of life, physics. What you are, is just as much an effect of the forces that work on you, as the molecular reactions that go on within you. The origin of these forces can be anywhere from your-self to the sun that provides the energy that runs life.

Pascal probably doesn't realise that he has just endorsed my view in the original post. Is life really just a matter of physics, chemistry, mechanics and such ?
