Yes, my belief that there is an invisible, flying, horseshoe-crab-like creature that follows me around sometimes. You know once I figure out how to capture the darn thing I'll be famous. I'll just spray paint it and show it to everyone, they'll all be sorry they laughed at me then, won't they? Also, I think it'll make a good pet.
Now, prove this isn't true.
I can't. It could be true. Although I doubt it, your belief in this creature might actually be rational. Personally, I would recommend professional help though.
Great, present some of this fabled evidence already. Hopefully, it will as irrefutable as the fact that life existing on Earth shows that life is possible.
Where in "There is evidence of the existence of God" do you read the word "irrefutable?" I never said there was irrefutable evidence of God's existence. I previously said that there is irrefutable evidence of the
possibility of God's existence -- just as irrefutable as evidence of the
possibility that intelligent life exists elsewhere.
Yes it does. There is nothing that separates Earth and this solar system from the rest of the universe. The stuff that makes up this solar system is abundant throughout the universe. The physical laws that exist in this solar system appear to exist throughout the universe. If it is possible here, it is possible throughout the universe, because there is nothing fundamentally different between the two.
If you have irrefutable evidence that the conditions necessary for the emergence of intelligent life are not unique to Earth, please present it.
We have irrefutable evidence that it is possible here, so it logically follows that it is possible throughout the universe.
We have irrefutable evidence that it EXISTS here, so are you saying that it logically follows that it EXISTS throughout the universe? No, the reason it is possible that intelligent life exists elsewhere is because it's not impossible.
What does this mean? So by this argument, it is just as rational to believe my horseshoe-crab-like creature exists as it is to believe that God exists? Glad we agree, was starting to actually believe some of the people that said I was crazy.
I don't claim to know for certain whether one is or isn't more rational than the other. I simply said that neither are necessarily irrational. In the case of intelligent life elsewhere and God, I'm not sure how you would demonstrate that one is necessarily more rational than the other, but I'd certainly like to hear it. Otherwise, I think you'd be overstating things to say that one is necessarily more rational than the other.
No, but one can be more rational than the other based on the available evidence.
Yes, it's possible. Again, if you're asserting that it is
necessarily so, you'd have to demonstrate it. Can you?
They are not both unfalsifiable in the same way.
Unfalsifiable means that it cannot be proven false. I didn't consider that there might be "ways" of being unfalsifiable, but I'm willing to hear you out on this.
The existence of life elsewhere in the universe is unfalsifiable claim only by practical limitations. Theoretically, we could search every star and planet in the universe, and after finding nothing, know for a fact life elsewhere does not exit. Doing the same will not prove God does not exist. It seems by the very definition of God, there is no possible way of proving God does not exist.
We would have to know exactly what to search for in order to assure that we know for a fact that intelligent life doesn't exist elsewhere. In fact, if an intelligent being didn't want us to know of its existence, it could either "play dumb" (prevent us from recognizing its intelligence) or hide from us. If intelligent beings didn't want to be found, it is possible that we might never be able to find them. Even if they did want to be found, it is possible that we couldn't communicate with them and would fail to recognize their intelligence.
Like intelligent life, it might require God's cooperation to acquire proof of his existence. However, once we had his cooperation, there is no chance that we wouldn't recognize his existence given that he is omniscient and could ensure it.
The probability is not the only way to determine which is a more rational option. You can also use the quality of evidence used to support that the possibility actually exists to determine which is more rational.
Perhaps you could use quality of evidence to determine rationality, although quality of evidence is rarely objective. I doubt you could provide an objective analysis of the evidence of either in this case, especially considering that there is little to no evidence to consider.
In the case of life elsewhere, we have evidence that life is possible and logic to say that if it is possible here that it must be possible elsewhere (see above).
Agreed.
In the case of God existing, we only have a definition that makes it impossible to falsify the claim, like that irritating horseshoe-crab-like creature. I think I should name him, his description is kind of long to write.
How about IHCC? Oddly, IHCC, God, and intelligent life outside of the solar system are all entirely possible.
Both possible, yes. Equally rational, no.
Again, you might be right about that, but can you show that one is necessarily more rational than the other? If not, then to say something like "one is necessarily more rational than the other" would be an inaccurate statement, wouldn't it?
Who claimed that? I said we have empirical evidence to show life is possible, and logical reasons to believe that what is possible in this solar system is possible throughout the universe.
You said "Empirical evidence is better quality than poor definitions. Making one opinion more rational to hold than the other." I assumed you mean that you have empirical evidence of intelligent life existing outside of the solar system since that was the topic of the discussion. If you meant that there is empirical evidence to show that intelligent life existing outside of the solar system is
possible, that was never in question. Of course it is 100% possible (with or without empirical evidence). So is the existence of God.
