I don't follow any of the Abrahamic religions, but Messi is God's gift to the universe.
The universe will live for more than 10^100 years. That's a huge number. It's not really even comprehensible for us.
Out of that huge number, you are actually alive/sentient/consciously aware of this other fucking being who's even crazier than you are because he's the best footballer in the entire universe; yes, the universe, because what are the fucking chances there is another Messi playing the exact same game called football in some distant planet in our universe, at this exactly moment in spacetime? Not very good. Chances are, he's the only one, and this is the only really rational way to look at it.
And you're alive during this little fragment of the totality of the universe's life.
If anything can convince me of God's existence, it's fucking Lionel Messi.
