We all know the impact something minute like a virus can have (it can even kill you!)
Tuppence pointed out that viruses are not considered life forms, and a quick look at www.dictionary.com confirmed this.
This got me thinking: According to many evolutionist's views, first life started with a simple, self-replicating piece of RNA (what a lot of viruses are made of) that would later create DNA (what some other viruses are made of).
If a virus is 'non-living', but a piece of DNA, that contains a bleuprint for a single celled lifeform IS a life form, and theory suggests that RNA 'develloped' DNA, than it is quite likely that life came 'out of no-where'. Pieces of dead matter, COULD then become living matter. After all, the step from virus to bacterium is not very big.
