Atheism leaves too much room for error.

[Eilonnwy]

I find it really hard to fathom that we are on this earth with no reason or cause. That just seems too far-fetched to me.

Just because you can't fathom it, doesn't make it not true. That's an argument from personal incredulity. I find it far more likely that there was no underlying reason for us existing. Humans often like to apply meaning and reason to things, especially when no meaning or reason exists. We're really good at that.

But putting all joking aside. The universe and all life-form just didn't arise from nothing, by nothing. That is going against every law in science.

Common misconception of what atheists believe. No one says that something came from nothing. We don't know how the universe came to be before the big bang. We probably may never know, but that doesn't mean God did it. Just because something doesn't have an explanation doesn't mean you can explain it away with god. It's just that: unexplained.

Furthermore, the big bang cosmology is very hard for people to wrap their minds around. It makes sense in a scientific and mathematical standpoint, but that doesn't always mean our brain can understand it from a purely observational view point. Adrian posted a video in the video forums on common sense and showed how .9999.... is actually equal to 1. It flies in the face of what we consider to be possible, or make sense...but it does. So your personal incredulity says NOTHING about what is actually true.
