To be honest, I wouldn't.
Assuming God exists, he seems to me like the deadbeat father who cleans his hands of responsibility when it is needed most, only to just show up one day after you've grown up and acting as if he totally didn't abandon you in the first place.
I get the whole free will business, but I see nothing reasonable about being provided with zero evidence with the little clause, "Just trust me". I have a bit too much dignity for that. Baseless trust has gotten people into a lot of trouble and I see this no differently.
As for placing meaning to life, as an atheist, I have absolutely nothing to die for, except to finally rest, but that can come later. Too often, I have encountered religious individuals who seem to be in a hurry to reach the pearly gates. Some were even excited about the millionth prediction of the Rapture. If anything, it's actually religious people who don't put meaning to life, because hey, they're going to heaven and hanging out with the big man upstairs. It's sort of like throwing away an old device and getting an upgrade. Atheists have nothing to die for and everything to live for, because this is all we get.
