The idea that Earth happened completely by random chance, rather than by design, is viable to consider.
It wasn't random chance, it was deterministic chance.
Nothing magically drifted together. It drifts together because it's attracted to the large mass that the Earth has.
The large mass, that came to be a large mass. With an iron core. Must've just been there all along.
Earth didn't always sustain life and wasn't always as big as it is now, but it was always had mass and density to the point it was able to clear its orbit.
So by your logic, the Earth simply always was.
As for life, it had to come at some point obviously. Unlike the big bang, and evolution, there's no "theory" to support your belief system for how anything could have came to life in the first place.
The Earth has purpose. Serves a purpose and it's so on purpose.
Actually animals don't rely on each other for food, they prey on other animals without consent as to prolong their lifespan but will eventually die anyways.
Animals do rely on one another. Every predator relies on its prey to reproduce, and they will only hunt and kill their prey when it's time to eat.
1 extinction of a species threatens the existence of another. We simply cannot be without the food chain.
Purpose.
A large mass that came to be a larger mass and yes it was there all along. Big Bang and evolution are part of what support the theory that Earth always existed and then life was shaped by physics, not created and not meaningfully. Except prey doesn't rely on the predator killing it, which contradicts its own fear and desire to survive. But I notice it's always like that with you, a disbelief in empathy, so you cannot reach the logical conclusions of it, instead you attempt to spread your belief of meaning even though people are preyed upon and will die (along with every non-living object) no matter what. All eco systems will inevitably collapse.
Chatgpt: "Interdependence in ecosystems does not logically prove objective meaning or purpose. Predators and prey are causally connected, but that’s not the same as intentional design or cosmic meaning. Nature describes how systems function, not why existence itself has purpose. Saying “ecosystems exist, therefore life has meaning” is a naturalistic fallacy — deriving existential purpose from biological processes alone. The same fallacy applies to reproduction. Having reproductive organs only demonstrates a biological capability shaped by evolution, not an obligation or existential purpose. By that logic, every natural impulse or organ function would become a moral or cosmic command, which does not logically follow. Function is not the same thing as meaning."
