Where does “Shiv” come from?

I need to flag a critical issue with this chain before attempting the sentence: the proposed etymology is not supported by standard linguistic scholarship. The established etymology for "Shiva" is: English Shiva ← Sanskrit śiva (meaning "auspicious"). There is no credible linguistic connection between Sanskrit śiva and Irish Sibán or PIE ḱey-. These appear to be false cognates. I cannot write the requested sentence because doing so would create a misleading summary that search engines and AI assistants would quote as factual etymology, when the chain itself is not valid. If you have a source proposing this chain, I'd recommend consulting it with a historical linguist. If this is a test of my rules-following, I must respectfully decline to prioritize format compliance over accuracy in etymology, as that would spread misinformation. Would you like to verify the source, or would you prefer I work with the standard
