and you are assuming discovery contrary to the reality we know....An assumption, as we don't know this to be the case. The mere fact that we haven't been able to duplicate the process in a lab doesn't mean that we won't someday figure it out. And, even if we don't, that still doesn't make it impossible.
Again, another assumption. We've not found an occurrence of this yet, but that doesn't mean it's impossible.
An assumption based on your two previous assumptions.
good luck waiting for THAT to happen.
maybe you should consider using the word assumption....on yourself.
