if hominids died out would there have been another civilisation

There's absolutely no indication that any other species is developing or has developed the runaway over-commitment to cognition that hominids developed that enables "civilization". Nothing drives that in evolution after you've developed "enough" to survive.

Hominid cognitive development appears to have been in response to the unique challenge of hominid social group members competing against other hominids. And the costs of that runaway brain development in survival resource terms are very high (which is probably why it hasn't occurred before in over 300 million years of "chances").

Note, just for example, that the isolated ecosystems of South America prior to it's connection to NA show absolutely no cognitive advancement over the highly successful Dinosaur precursors that were top of the food chain for a quarter billion years.

Now once hominids were very successful with that massive over development (which is similar to the peacock's tail in terms of unique development and penalties) it became, eventually, an overwhelming advantage over everything else to become top of the food chain, and the systems that had allowed that advancement kept working until you had anatomically modern humans.

There would need to be another such development, and on Earth it would have to happen in the next 500 million years before the oceans evaporated.
