The first 'life' (i.e.self replicating 'thing') would most probably have been
DNA itself, RNA, PNA (protein nucleic acid), or some other chemical reaction.
Many have been hypthesised, including clay crystals...its a very good
argument, don't laugh!! Well thought out. If you like e-mail me and I'l dig
up the reference. The point is, nothing needed to be built using the DNA (or
whatever) as the original was not a cell, but merely a self-replicating

No you are not. No creature could ever possibly be spntaneously created, but
a could chemical process could evolve more and more complexity.
