Here is Practical Explanation about Next Life, Purpose of Human Life,

[Peebothuhlu]

this is the whole problem with life, it doesn't have a sound definition, long ago we used to think there was this life force that gave life to inaminate material, this was until it was discovered that substances only produced by living organisms were also able to be created with simple chemistry, once we figured out that life is just chemistry it lead to an explosion in medicine and other things alike, you can zoom into one of your cells which would be a complex eukaryote and you will find that no part of the cell is alive, its all just a series of chemical reactions partaking in a complex orchestra to keep the cell and the genetic material alive, so if your cells are not alive, and you are made entirely of cells, then you by definition are not alive, this is the problem with trying to define life, that's why i use the widely excepted nasa definition for life a self sustaining chemical system capable of darwinian evolution by this definition the simplest living thing earth is a viroid, a viroid is just a looped strand of rna that infects plant cells by hijacking one of there proteins called rna polymerase 2 to continuously replicate over and over, they are thought to possibly be some of the last living reminets of an rna world.

Well... yes.

Welcome to one of the 'Hard' roblems in reality. 

Depending on your way of thinking about reality, that is.

For me? I am amazed by the things I'm slowly learning on acasual basis about cells and biology adn stuff. Then again, I'm also amazed and fascinated  when I read my favourite daily blog about astronomy and the things suh people are seeing in the skys around us.

As for "The RNA world" ? I think they've found that DNA and RNA could exist structurally in the early abiogenesis phase but the article escapes me at the moment.

Then you have the whole "Consciousness" and at what level of organism does it manaifest?

Since there's evidence that single cells critters can and do show signs of 'Panic mode' when being attacked/'Eaten' by other micro organisms at one level and then the active hunting behavious of things like the 'Australian Box jelly fish'. Something that's pretty much just rudimentary sense organ controlled death swimming through the ocean.

It's a funny old world, in-it?

Not at work.
