I am not going to provide an argument, just some quick thoughts on the matter. For me I don’t see atheism as very realistic. But, that is based on my own combination of experiences, reasoning and intuition, as well as an openness to God. The answer to this question will depend on the person’s bias. I don’t think one could be entirely unbiased. Aquinas gives us 5 ways. I find the argument from design, as well an argument for the first cause and the argument for a self-existing being, the contingency argument to be persuasive. As well, Dr. Craig makes a number of good points. The impossibility of an infinite past for instance. And to top it off I think intuitively it just makes the most sense we are here because of some divine intelligence. It just doesn’t make sense to me that the universe exists spontaneously. I guess that flows into the argument of design. But at some point you have to step back and ask yourself is all this really just here by chance? If you don’t think so then you are not an atheist. Even the laws of nature are evidence of design. Where do they come from?
