What is the ‘point’ of earthworms? If they all disappeared tomorrow, would there be any impact? (Other than a food source loss for some animals)

As above. Sorry if this is a silly question!

I realise there is no ‘point’ to any particular animal or plant, but you often find that various species provide some sort of benefit (e.g. plants giving out oxygen, those birds that clean crocodiles’ teeth, spiders eat a lot of flies).

I just wondered if worms are particularly ‘useful’, because they don’t seem to do much from what I can tell

To answer OPs question from a gardening perspective: earthworms, as well as all other bugs like earwigs or even aphids are beneficial to the garden in a variety of ways. For worms, they aerate the soil which keeps it loose and well draining and they eat dead plant tissue, animal tissues whatever, and then they poop, and that poop is usually left behind in the soil as they chug along for plant roots to utilize.

They also are great for composting, and you get worm tea (their pee) and worm castings (their poop) for fertilizer for your plants.

essentially think of it like this:

If you ever had a hamster as a kid and it died and you put it in a box and buried in the ground then a few months to a year later you notice the wild grass or flowers are doing REALLY well right where you buried the hamster? That’s because of worms! (And mycelium but still) that ate it, and then digested it, and pooped it out.
