We all are here against all chances. In the _observable_ universe there are this many cubic meters of space: 35000000000000000000000000000000000000000000000000 00000000000000000000000000000000 (literally, and the total volume of all universe might be vastly more), and you have ended up on one of 1,000,000,000 galaxies, and to the perfect region of that single galaxy's area of 1,000,000,000 stars where life can potentially exist. In that region of the galaxy there is a small star, our sun, which of all its planets and their moons it has chosen to support life here, on earth, through billions of years of evolution and give you, a tiny speckle of dust, a chance to experience the world around you.
Now you come to me and start wondering if life is worth living, and I'll whop your ass because you owe your existence to everything else, and nothing owes its existence to you.
