Does God exist: A hopefully civil and fruitful debate

Is there an all-knowing, all-powerful and all-loving being?

Here's the kicker for this...

First, lets take a step back several thousand years to the dawn of religion as we have come to accept it...
-a "being" comes to earth, many times more intelligent than what we are back then
-immediately any human that interacts with said "being" will be in awe of his intelligence
-"being" appears to those on earth as all-knowing, all-seeing, all-loving because of what it appears "being" can do

Now, fast forward to present and look at our definition of God through that lens. At this current state what actually was and what we now perceive as are completely different nowadays.

The issue with any debate over this topic, is that outside of belief, there is no way to prove or disprove without any physical evidence the existence, or lack thereof , of God.

Given the fact that the Bible was written by a man who supposedly was being told what to write by God, there is no way to know for sure if this is true.

Scientifically they have shown that the milky way galaxy is one of the youngest in the known universe. Therefore it lends to think that there are solar systems and galaxies many magnitudes older than earth and therefore could easily have beings same magnitudes smarter/more advanced that we are and to even modern day humans would appear as gods based on what their inconceivable technology would allow them to do.

@Kalovale But isn't the very discussion of God's existence dependent on how we came to interpret who/what God is? By stating "I'm interested in being(s) that is/are all-knowing, all-powerful and all-benevolent." is on it's own merit now saying that you know they exist and this is a discussion of whether or not they do, therefore my case still stands as this whole discussion ultimately stems from the perceptions we have as humans about what does or does not exist.
