John and Joe have an argument. John thinks there is a god and life after death.
Joe doesn't think there is a god or life after death.
Who's right?
Isn't their argument pointless being neither John or Joe can speak with the dead, so in reality neither one knows?
Being neither one knows why do they argue? Is it just human nature to argue and we will find reasons to do so regardless?
I don't think there is much difference between Joe and John since both are not sure what they believe. Both of them think one way or the other. It seems either of them can shift from their position by persuasion. So, good that they are discussing or arguing. There is opportunity to learn and figure out things even with lack of evidence.
I guess that should address the OP but let's go a step further and really try to find out who could be right...
I believe - if you believe in something - it has to come from the gut. "To think something" and "to believe in something" is not the same thing!
Even in the case of an Atheist - for non belief in the existence of god/God - one has to be confident in his stance otherwise he could easily be an agnostic.
Furthermore - it is not clear what Joe really believes in. Does he believe in evolution theory or does he believe aliens created him? Maybe he thinks his forefathers 'poofed' into existence.
If Joe is an Atheist and if he believes in the theory of evolution then we can go on with this hypothesis.
Let's just say Joe is an Atheist and John is a theist. So, lack of believe in a creator means Joe believes he was created by chance and via evolution process and John may also believe in the theory of evolution but at least he believes a God is there behind the whole thing. John may also believe he came from Adam but we don't know for sure.
In either case,
Joe believes in "chance"
John believes in a "God"
For Joe to believe in "Chance" - he would need to believe that complex life has formed on earth by evaluation process where billions of things have to be just in the right order to make it happen. But before billions of things has to be in right order for evolution to even take place successfully - the earth has to be created also by chance. Before that our solar system and before that our universe and so on. Everything has to be created randomly and everything has to be in right order and within right settings to allow life on earth.
Lets just go to the beginning of creation! First of all - the concept of "Time" has to be created by itself. I don't think we know enough about "Time" and its relation with the universe but we do know that at a certain point in "time" our universe must have been created in a process that collaborates with the "Big bang theory". Whatever way the universe came into existence - it requires a beginning. After that point in time - billions or trillions of galaxy were to be created randomly by chance. A few steps forward - our galaxy (the Milky Way), our solar system, sun and finally when gravity pulled swirling gas and dust in to form our planet earth - we got our home world! The earth had to form at a precise distance from sun and it needed to contain all life sustaining elements and it needed to rotate at precise pace to create the right gravitation pull and also rotate around the sun at a precise distance where the temperature is just about right to have a habitable environment. After all that - the Darwin's theory kicks in and step by step (in a very complex settings) all the species evolved through the evolution process - finally after a process that started billions of years ago - Joe came into existence! For that to happen - so many things had to be just in right order since the beginning of the universe.
The probabilities of all that happening in the correct order and correct environment is something that can be compared to throwing a small pebble in the ocean and hoping to hit a small fish that is hiding in there. Actually the ocean would need to be billions of times bigger than what we have on earth and the pebble and fish need to be billions of times smaller in size. Now imagine hitting that minuscule fish with the minuscule pebble in the a super gigantic ocean.
So, Joe would rather believe in such "chances" rather than believing in a Creator because Joe claims he doesn't see any proof of a Creator!
You decide who is right!
On a side note - I believe John can say that the proof of the creator is already there in all the creations.
Forget about talking to dead people, forget about the mountains, the trees, the bees, the birds - just take a look at anatomy of a human body. All the complex organs started from one cell. How the artery and vein travel through the body and through bones and yet hardly ever get compressed, how food travel through about 22 ft of intestines, how everything in the blood maintains such accurate levels for body to remain healthy, how much blood the heart pumps a day - all that should signal some higher authority is behind the blueprint of a human body and it is not just random evolution.
All the physics the chemistry the biochemistry the genetics or biological information science (DNA) involved in the creation of human body should suggest a purposeful intelligent designer is behind it. But Joe wants to believe all that happened due to necessity, evolution and chance.
But even if Joe is right then where did the consciousness come from?
So, I think it is good that Joe is discussing with John. Let it be a constructive argument.
Meaningless argument - on the other hand is not warranted and neither Joe or John should participate in that!
