Of course. The Roman pantheon, and the Greek before that, were long after the "gods to explain natural events" explanation took root, though. If you look at them, though, they do contain explanations for the creation of the universe, the world, the underworld, time, aspects of the world (like oceans etc) and pretty much everything else. You can find all of them in there representing the early understanding of how things came to be and why things are. The gods were their explanation for such things. In the Roman pantheon, volcanoes were caused by Vulcan, for example.
Sure, you then get gods of beauty, wisdom, love, war, etc, i.e. the abstracts, but they are also natural things that they sought to explain. Why is someone
wiser than others? Oh, they've obviously been blessed by Athena, etc. Abstractions need explanations. They're more nuanced and complex than the physical (e.g. volcanoes, storms, droughts, etc) but I imagine they reflect the wider understanding of the human condition within the natural world. But within all of it does seem to be the idea that the deity explains the phenomenon, whether the phenomenon is physical or abstract. Then add bells and whistles, and bake in the oven at gas mark 4 for 30 minutes, and you get the "guide" that some priest slaps on to the deity.

That's the Greek/Roman pantheon, anyway. These never evolved to monotheism but were instead simply discarded in favour of the Abrahamic One God when Christianity rolled through what is now Europe.
On that front, the Abrahamic monotheism was borne out of the Israelites worshipping Yahweh exclusively, although prior to this, as part of the Canaanite religions, Yahweh was initially one god out of a number that were worshipped, again each with various attributes as per the Greek/Roman. The idea of a single God that takes care of people is then just an evolution of this, I presume. Maybe they just had better marketing than those who stuck with polytheism.
But, sure, gods were and are more than just explanations, although I do think it's likely that's where it all started. That and animism.
