I believe someone already mentioned this, but we know that Lil Nas X survived the snap because Shaun and Katy are singing Old Town road in a bar in Shang-Chi. But I’d like to point out just how close these two events were, (the release of Old Town Road and the snap).

The song released on December 3rd, and later re-released with Billy Ray Cyrus on April 5th, 2019.
So, essentially, in a matter of months:
*half of all life is destroyed, governments are in ruins, world consumed with chaos*
Meanwhile Lil Nas X:
