I voted yes, in the sense that you change “will” for “would”. If it is a more ‘will it actually happen?’ type question, I have no idea. Perhaps, and if it did, yes, I think it would change many things.
It depends how and where it is discovered.
Is it life, Jim, but not as we know it?
Is it intelligent life of just self-replicating chemical compounds?
Or did it discover us?
