What if Aliens don't have DNA, but instead have an entirely different system?

If there are aliens on planets circling a star other than our Sun, chances are they have DNA very similar to ours. Different systems might not even be possible

Yes, WHAT about it ? Since we don't know any aliens, this is a particularly pointless speculation.

We'd have to meet an alien to find out.
