Building Blocks

We have had enough issues recognizing life on Planet Earth, that I am not sure we would recognize life on other planets even if it looked right at us. I have hopes that on other worlds we will find evidence that the building blocks of life on our planet exist elsewhere in the cosmos. Finding DNA, RNA, an amino acid or a simple protein on some of these distant worlds would be sufficient to suggest that life here probably began somewhere out there.
