Neo," noone can say for a fact that the Universe has not existed forever."
No one can say otherwise either.

Neo,"Scientists need to explain things rationally so they believe that the Universe has a beginning and after doing extensive research that possibly cannot be taken as fact."
So if you cannot take the logic and reasoning presented by scientists then what do we have ? lol That is like that debate by Republican congressmen arguing that its their(scientist) job to write theories and present papers... but that does not mean I believe them. You cannot be selective.

Neo,"You can choose to believe they are absolutly correct about things like the big bang that happened billions of years ago or you can keep an open mind about it and believe that perhaps the universe is infinite :)"
Sure.. I will let you believe that it is infinite. http://map.gsfc.nasa.gov/universe/uni_shape.html
