I would say that the likelihood of there being other life than just on earth is relatively high, certainly higher than the likelihood of the Exodus every happening or the Conquest of Canaan as described in Joshuah or of any prophecy of Jesus standing up to examination.Anyone so limited that they can only spell a word one way is severely handicapped!
I'm sorry but why can we not conclude that "all chemicals have the same behavior on other planets as they do on Earth" since ALL of the evidence shows that they do?
And in addition, who is saying that abiogenesis will inevitably happen?
So far it looks like all you have are attempts to change the subject and misrepresenting what folk say as usual.
You do understand that there are means of remote testing for things like chemistry, nuclear reactions, physical properties, even things like amino acids and that so far every such test has shown that chemistry and physics are about the same everywhere?
If things behave the same what reason is there to think things will not behave the same?
