I don't know why we are still talking about purpose and meaning. The word "meaningless" in the context of the op does not mean "without meaning or purpose "! It is הֶבֶל hebel meaning futile, vanity, or litterally "chasing the wind"
No, I fear I do not get it. "Futile" would mean "serving no useful purpose" "Vanity" would mean "empty of meaning or value". So what you said it means is just what you said it doesn't mean in the previous sentence.
So I can only conclude that you have no idea what you are talking about.
"hebel" also isn't literally "chasing the wind". Wind, yes. Breath. And then
figuratively something that is fleeting, something that you cannot catch, something... well, futile, vain, empty, meaningless.
But again here you are wrong: catching the wind might not be achivable...
chasing the wind is possible.
And in this regard you still haven't told us why you think that "anything with God" is meaningful, not futile, vain or not like "chasing the wind".
It is something that I have known for a long time, but never seen in such a condensed form as in the last few debates that I participated in. Christians try very hard to demonstrate that our - the unbelievers - worldview is so bad. Immoral, evil, meaningless, futile, hopeless, worthless, purposeless, to be discarded and destroyed, something that we will come to regret eternally. The worst that there is, that there could be.
But when challenged, they show themselves to be completely incapable to demonstrate that their alternative is better in any way.
