Cosmic 'Booze' Created In Quantum Brewery

To be exact, 'precusor' molecules were found so far. They have like half of complexity of what we are talking about, which makes it quite probable that amino acids are out there.

But there is a far way from single particle of adenine to DNA chain. (a lot, lot further than from single atoms flying in space to group of 7or so atoms in adenine). And then there is a mystery of DNA/RNA replicating with help of cellular structures which themselves are encoded in DNA...

It is a bit like throwing a CD with cd-ripper program on top of pile of pure silicon wafers, hoping that somehow they will turn into PC with CD drive, read the program and start copying the CD around.
