The Creator EXISTS. He is existing. Now we must remember, Allah's existence is not abstract, only His names and attributes are. The creations prove that the Creator exists. If one was to step outside their house they might see some cars and trees. Now, where did these cars and trees come from? One might say "oh companies manufactured those cars and people planted those seeds for the trees." Ok. But where did the seeds and the parts for the cars come from? A non-believer might say "I don't know man they was just here when we got here." Ahh! Ahh! Ahh! There goes your answer right there. Well... not really. The belief that they was just here when we got here is a contradiction and very untrue. It is impossible for the trees to just have "been there when we got here". THEY WAS PUT THERE BY ALLAH. ALLAH. ALLAH. ALLAH! Allah exists eternallyl, and it is He who makes other things exist.
