I'm not very surprised, but it may be due to my unfamiliarity with chemistry. I know other amino acids have been identified from our own solar system. It's yet another sign that life arising in other solar systems is quite plausible. No one knows how plausible, but I have a feeling chemists have a better idea of that than I do. I have an uncle who is a retired chemistry professor, but also a Christian, so I've never asked him about his views on abiogenesis. At least he's not a Republican.
Anyways, I hope we find life outside of Earth someday. Preferably within my lifetime.
