That thread didn't go too well, too many alteria motives.
If we were to do this in a scientific way. We would need a definition of the term "god"
Then we would need to workout what tests are needed to be passed for an entity to qualify.
We would need a willing participant to partake of the tests.
We would need some impartial observers, video footage, documented results and reseaons why only a god and no other entity could pass those tests.
I think stating "what evidence would it take" is jumping the gun.
e.g. if the definition of a god was "An intelligent being that created the universe"
Well, we have no clue how the universe got created. There is no proof of anything in this department.
TheJackle has a good arguement against this. If there is no energy or matter or space then:
1. What is god made of?
2. Where does god reside?
3. Where does this god get its intelligence from, given there is no energy, matter, data, information to base knowledge or intelligence off of?
Also "creation of the universe" is a bit vague. Are we saying creation of the energy/matter that makes up the universe or are we saying the initiator of the big bang (given that the energy/matter may have already been there is a rather large black hole?
If we state that god is "the entity that answers prayers"
We would then need to prove that prayers are being answered. This would beg the question, whose prayers? How often? Are these answered prayers any different to the natuarally occuring events. Do prayers need to be spoken outloud, do prayers have to be requested from a viruous person? Do prayers have to be directed towards a particular god?
You'd think statistically that this one could be proven one way or another.
What else is the definition of a god and how can it be tested?
BTW we seem to be trying to find something that matches a definition rather than finding something and then coming up with a definition of that something and giving this definition a name (noun).
