@MolkosTeenageAngst you're arguing against something I haven't asserted. Under the "intelligent design" theory of creation then God would indeed have deliberately created all those things and designed them to be just so. Which is one of many reasons why intelligent design isn't part of my beliefs. Arguing against the existence of God by pointing out the obvious flaws in the idea of intelligent design is a straw man.
I believe God created life and life includes all these things because life is a constant struggle to survive between a myriad of beings whose survival and thriving are mutually incompatible with one another and from that struggle,, amazing and wonderful things come forth which would never have existed without that struggle. The virus and the bacterium are struggling for life too. The antelope and the cheetah are both struggling for life and when the antelopes survive and outrun the cheetah, the cheetah cubs go hungry.
Life doesn't just happen automatically. The probabilities against it are enormous. Before you even get to whether or not a planet can evolve life, there's a question of how the physical constants of the universe are set such that even molecules are possible - the Big Bang could have caused a universe where those constants were very slightly different such that there was no possibility of molecules forming, just an infinite expanse of dust. If you can get thecuniverse going in such a way that stars and planets form, that doesn't necessarily give rise to life. The properties of that very simple molecule of water, which is vital to life as we understand it, would be very different if those physical constants were just a fraction different, and yet water exists. Even so, among billions of solar systems the probability of there being a rocky planet just far enough from a stable sun that water can exist in liquid form and an atmosphere with a sufficient magnetic field to ward off solar storms and make life even possible is such and incredibly unlikely thing that it's frankly a miracle - and one that took several billion years to achieve
Maybe it's a shame that the God who creates with a single word a perfect heavenly world in which there is no struggle and no suffering doesn't exist, but I don't think it's very valuable to argue against the existence of something whose existence isn't being asserted.
Yes God knew that creating life in this way, by means of physics and evolution, would intrinsically lead to suffering. That's the tradeoff, the grief and the pain and the joy and exultation are one package. It is therefore intrinsic that God must incarnate as part of the creation and experience that suffering first hand because to choose that tradeoff but to allow the suffering only to be borne by others and not oneself would be abhorent.
There is of course way more suffering in the world than what is required as intrinsic fallout from the nature of life because of choices made by us - moral beings who could choose better. The suffering caused by parasitic wasps etc isn't 'sinful' - it is creatures acting in accordance with their evolved nature with no understanding of the bigger picture. Humans are only capable of sin because they have the capability of understanding the consequences of their actions and the suffering they are choosing to cause, and they do it anyway.
