Death is inevitable but most people don't die until they're 70 or 80. For those that meet with the inevitability of death way before that, e.g. by way of a terminal illness, no one sane would not stop to question why. I've heard all sorts of reasons: the religious like to chalk it down to "God's plan"; the less religious and probably agnostic like to talk about "destiny" or "predestination", which is variation on the idea of "God's plan". These two ideas imply that there is a larger force at work in the universe, with the only difference between the two being the mode of identification of the said larger force (for Christians - a God; for non-Christians - destiny, fate, cosmic forces, whatever). But it's glaringly obvious to me that these ideas are borne out of a weak human need to find meaning in what is really dumb luck, sheer coincidence. In other words, the reason why something bad happens to someone but not someone else is because that person is unlucky; when two people meet and fall in love, it's not because "fate brought them together" but simply because they coincidentally happened to be at the right place at the right time. No point trying to dress up this fact, stark as it is, by reference to a higher power, some sentimental yearning or longing for a "larger purpose" such as "fate" or "destiny" so as to justify human existence and give it seriousness. Nice try. But I don't buy it. Oscar Wilde was spot-on when he said that the basis for optimism is sheer terror.
Well, I wouldn't try to assign every and any small thing to a higher power, however it's - as you say - glaringly obvious that there are laws at work everywhere around us; the law of gravity, the laws of thermodynamics, the laws of movement and plethora of others.
And they are as good on Earth as they are on the Moon, on the Sun or in another galaxy. Odds that all that is just dumb luck are monstrously small, probably even worse than for Shakespeare's Monkeys.
