Question

In which story did a rainbow appear to tell humanity that no such flood would ever occur again?

In which story was the flood sent to put out a great fire?

Answer 1

Short answers:

- "All the humans turned to clay" — That motif appears in the Maya creation story recorded in the Popol Vuh: the first humans were made of clay (mud) and when the rain came they dissolved/melted back into clay.

- "A rainbow appeared to tell humanity that no such flood would ever occur again" — That is the Biblical story of Noah's Ark (Genesis 9), where God sets the rainbow as a covenant sign.

- "The flood was sent to put out a great fire" — I don't have a single famous, universally known flood myth that is primarily described as being sent to extinguish a great fire. Some indigenous myths (various Native American and Australian Aboriginal traditions) and a few Mesoamerican variants link floods and fires in that way, but the specific tale you mean might be one of those local traditions or a lesser‑known version of a flood myth.

If you can give any more detail (culture, character names, a phrase from the story, or where you heard it), I can try to identify the exact tale for the third item.
