A search for the meaning of life is a search for real living, that is, a search for death. As example...
Imagine that we are having wild sex with our favorite partner. Are we searching for the meaning of life now? No. Who cares about meaning when we are fully consumed by really living?
When we're really living, we are dead. Not our bodies, but the internal collection of abstract thoughts called "me".
Thoughts are like photographs of reality. These mental photographs are very useful, but because they aren't the real thing they point to, they are a second hand experience of reality, just as any photograph is. Thus, while thoughts can be quite compelling sometimes, this second hand experience lacks adequate psychic nutrition.
Looking at these mental photographs is like trying to have sex with a picture of our favorite partner, instead of our favorite partner. We can do it, but it's just not the same. Something important is missing.
So while we spend much of our lives in this second hand experience called thought, thinking endlessly about me, me, me, me, me and more me, we become hungry. We're not sure for what exactly, but something is missing.
So we go looking for something to munch on, something to fill the hole. If we're grand philosopher types, we may go searching for the meaning of life, because that sounds stimulating, a big project that might fill the hole we can't quite put our finger on.
But in the end, the meaning of life is of course itself a thought too. So it too is a second hand experience, and never quite fully satisfies. So we go looking for something else. Hey, maybe arguing with somebody else's meaning of life will work!

But that too, is just more thought, more second hand experience, more empty calories.
To illustrate, if arguing with other people's meaning of life could satisfy us, then after a couple visits to a forum we'd be good to go, mission accomplished, hunger satisfied, and we wouldn't have to keep coming back to the forum day after day after day, for years on end.
To debunk my own post, if I really knew what I was talking about I wouldn't still be typing.
