It's not so much that there is no meaning (at all), it's just that, even if there is meaning, it's inconsequential. Humans are nowhere near as important as most people seem to believe. The only reason you're able to enjoy anything at all, or ponder the concept of "meaning", is because God chose to create you. Maybe He didn't foresee how stupid/arrogant a lot of people would end up being. Maybe we were just a "good idea" in God's mind, but in practice, turned out not so great. Whatever the case, all anyone should be concerned with is enjoying life. If there was a universal mandate for what humans must do, "enjoying life" would be that mandate. Of course, it isn't a mandate, because God doesn't care what you do.
