Subject: i know how DNA was first created but how did the cell first occure?

i am puzzeled as to how the material around the DNA knew the code in which 
the DNA is ''written''. I know roughly how the DNA first occured( by 
passing an electric current through some soert of mineral pool and the 
chemicals need some how come together) but my question is to how the 
material around the DNA strands knew the language and how to respond to 
it.Because within the DNA is the commands for the surrounding tissue, for 
example if it is a specialised cell like a nerve cell the command is to 
create a nerve cell but how would the material at the beginning know how 
to do this. This also brings up another query of mine how exactly can we 
be alive  if we are just a bunch of atoms carrying out chemical reactions 
and dont tell me respiriation makes us alive because it is just another 
chemical reaction.
