Not quite. While abiogenesis and more specifically the RNA hypothesis, is geting more and more solid as a theory for the apparition of life with a latest experiment yielding impressive results, it's not the only possible explanation. Panspermia, the idea that life would have emerged on another planet and ''crash landed'' on Earth while frozen in comet's ice is also a possibility. In that case of course, it simply ''moves'' the problem of the emergence of life to another theatre than Earth, but it's still a valid, if marginal, theory for the apparition of life on Earth. On the other hand, spontaneous generation of life has yet to be observed, let alone its process explained, thus is a ''not even wrong'' type of explanation.
Repeating, you have a problem of infinite regression with panspermia. Were the aliens themselves panspermia, abiogenesis'ed or Created?
"We don't know the alien world's climate, vulcanism and melting pot of chemicals" sounds like a just-so story to me. Sorry.
