Blosted,

It was Max Bernstein who passed UV through some polycyclic aromatic hydrocarbons and created organic molecules of quinones, ketones, alcohols and ethers.

Also, Stanley Miller, a chemistry student passed electric current through ammonia, carbon dioxide, hydrogen etc. to create building blocks of life - amino acids.

So, we see that methyl alcohol could have been produced by high energy electromagnetic radiation through PAH that is said to be so most abundantly found organic material in the universe.
