I think it is strange when people (usually religious folks) believe 'the unknown' with such extreme certainty. I'm not saying that they are wrong, but I personally can't buy it without having very firm evidence. Faith is an odd concept to me.
I don't feel that I have a complex enough brain to try to understand the mysteries of the universe. I also don't think the majority of the people in this world have any better capacity to understand it, except for a few individuals that seem very highly connected to something more powerful than our individual souls.
I'm open minded to many religious concepts, but don't have absolute faith in anything because I think it is silly for the average person to pretend to know how the universe works, how it came to be, and what happens to our souls when we pass.
There are some exceptional individuals that are clearly higher functioning than the rest of the world.
One example is Albert Einstein.
If he is suggesting the possibility of a God that is 'that which exists', I'm very open to that being true. I will believe this highly functional person's opinion over some random book of religious texts that some random person wrote in ancient times.
Albert Einstein (1879-1955)
Einstein is probably the best known and most highly revered scientist of the twentieth century, and is associated with major revolutions in our thinking about time, gravity, and the conversion of matter to energy (E=mc2). Although never coming to belief in a personal God, he recognized the impossibility of a non-created universe. The Encyclopedia Britannica says of him: "Firmly denying atheism, Einstein expressed a belief in "Spinoza's God who reveals himself in the harmony of what exists." This actually motivated his interest in science, as he once remarked to a young physicist: "I want to know how God created this world, I am not interested in this or that phenomenon, in the spectrum of this or that element. I want to know His thoughts, the rest are details." Einstein's famous epithet on the "uncertainty principle" was "God does not play dice" - and to him this was a real statement about a God in whom he believed. A famous saying of his was "Science without religion is lame, religion without science is blind."
