It's looking more and more likely...sort of. In fact, what might well have happened is that amino acids formed in deep space and were carried here by meteorites.
All four of the base amino acids that form DNA and RNA have now been found raw in meteorites, but they could also have formed on Earth.
However, if these amino acids form in space, it makes it more likely that different ecosystems will be biologically compatible...that is that DNA or some form of it may be a universal or near-universal coding system for life.
We'll see.
