Nietzsche said that with an infinite amount of time and a finite amount of matter the universe must be on a big loop. Everything possible has happened and will happen again. The same atoms that formed your body will form again, and have already done so an infinite amount of times. Descarte tried to prove physical reality/existence through the existence of God. His proof of god's existence was simply that God was infinite and therefore infinitely perfect and HAD to exist.
These and many more philosophies based their proof of existence on the concept of infinity. By our very nature the human mind cannot fully comprehend what infinity is. Trying to understand infinity is like a dog trying to understand English punctuation. The dog can see commas and accents, but doesn't have a clue what they mean, let alone that they are a means of communicating. Trying to explain it would just confuse the dog even more (which sounds similar to the headaches of actually trying to read some of the most famous philosophy books). The human brain can define infinity but never actually comprehend it. Based on this fact it should be impossible for any man or woman to know the reason or rhyme of the universe. Because of this it becomes laughable to believe in any form of defined divinity.
That is not to say that religion on the whole isn't at all useful. Without religion it would much harder for the Shepard to keep his precious sheep in line. Religion, or its pure doctrine, provides good bases for building a successful society of self aware thinking beings.
All of the prophets; Krishna, Jesus, Mohammad, etc. all taught the ideas that keep our animalistic tendencies at bay. It is human nature to rely on our instincts, but our ignoring those instincts (like say that to take what we want without asking) can end up being very beneficial. We can credit the prophets with saving us from an anarchic hell. Unfortunately, (to quote MJK) "someone had to stick their finger in it and fuck it all up." In the first instance of absolute power corrupting absolutely (so-called) pagan religions humbled and frightened citizens of the first organized city states in ancient Mesopotamia. Later kings and emperors of great civilizations would hide behind their relationship with the gods (which was presumed better than everyone else's) in order to control the flock absolutely.
At this point I have strayed from the true purpose of my writing. My point is that modern philosophy (that of the last few millennia) is continuing to go in the wrong direction. Most philosophy focuses on why we are here or if we actually are here at all (which is a moot point because if we AREN'T here it certainly appears as if we are going to keep lucid dreaming for a long time). This is a lost cause due to my argument of the concept of infinity presented earlier. Instead of having a preoccupation on something we can't understand we should turn back on ourselves and ask "why?" These explanations of life are all a futile attempt to imagine there is a way out. These philosophers imagine (whether true or not) that there is something more to this life. Most of the time the reason must be that they are unhappy with the brutal cold reality in front of them. We should examine (philosophize if you will) why this life is so awful. What this means is that Karl Marx and his contemporaries were far more important then they knew. Marx's concept of alienation is a fantastic explanation for the reason of unhappiness with our world. Unfortunately Marx went too far and began instructing ways to exterminate alienation. This Marxist theory when tried in real life always fell through because no human can run a perfect system.
Even if the rules are handed down by GOD it only takes one human to stick his finger in it and ruin it. Yes, I'm referring now to the bible. Just how much of that "King James" version do you think was written from the word of god and how much from the mouth of king James? This idea is not an affront to Christianity, the bible I‘m sure still contains a modicum of its original content, but the fact that many people have meddled with it over the millennia means that contradictory passages must be taken with a grain of salt. So , to come to a conclusion (which I'm sure you may have though would be lacking by now), nothing in life is absolute and everything is therefore precious and worthless at once. It is up to us to decide which idea we like best.
