God: To be or not to be...Is that even the question?

The past couple of days I've spent some time reading the blogs of folks who identify themselves as atheists. It's been fun. These folks have some really good points that, apparently, aren't being addressed by theists of any flavor. One of the recurring complaints is "I don’t think I can accept that without explanation or evidence." I completely understand and respect this position. For people to question and investigate things is inherently human. (Not cat-like curiosity.) I am one of those Christ-followers who embrace the scientific community. Do I think that science knows, or can know, all of the answers to all of the questions that all of the people on this rock can ask? No, not really. On the other hand, do I think that the Bible or any person who searches and studies its contents can know this either? Still, no. One of the respondents to a blog I checked out identified himself as a physicist. He wrote, "In physics and mathematics, special circumstances hold at singularities.  Within classical big bang cosmology (which is regarded as incomplete by essentially all experts, even with the addition of semiclassical inflationary models), the Universe began with a singularity." He then suggested with these special circumstances it's possible that the Universe was causeless. I really hope that he's not correct. I, like a good share of the rest of humanity, would like to think that we, as well as the Universe, have some reason, or cause, to be here taking up space. So, please, scientific community; keep looking!
The reason I can encourage those who seek is that I am not threatened by this. And, I don't think that the God I follow does, either. I believe that this God has gifted humankind with a mind that questions and seeks. This mind is creative and imaginative, just like the One who imagined it.
In response to those who demand explanation or evidence. Sorry, can't help you. And, to be honest, I don't feel that I have to prove a thing. If I am truly to follow Christ, I must, with him, state, “Why does this generation seek for a sign? Truly I say to you, no sign will be given to this generation.”
Truthfully, I don't see any reason to engage the discussions put forth by atheists. I really don't think that discussion is even possible when there appears to be irreconcilable differences. They want proof, all I can offer is experience. Like one blind person in the Gospel narrative I can say, "I know that once I was blind, but now I see." No one can share the blindness I experienced, so they cannot possibly understand what I now see. Please, I hope that no one thinks that because I don't care to debate these issues I don't care for those who would debate. I do. These are people who have meaning and worth. Their opinions are important, but they are only opinions. I cannot prove that God is a loving, caring Being who lives outside, yet inside of our physical universe. (Please, don't make me try to say that again.) Nor, can they prove to me that there cannot possibly be any such Being. In the meantime? I suppose we can agree to disagree and get on with life. For some of us, that may be much longer, (shorter?), than we think.
