Note: I have limited knowledge in these matters. But I am a curious person and go with reasoning.
I want to know that in which all Hindu's divine/sacred scriptures lord Śiva has claimed or explicitly asserted that he is a God and he should be worshipped.
In Christianity: It is nowhere mentioned that Jesus himself claimed to be a God and asked to worship him.
In Sikhism: In their sacred scripture Guru Granth Sahib, possibly nowhere Guru Nanak claimed himself to be a God and asked to worship him.
In Islam: Somewhere (possibly few places) Allah has claimed to be a God and asked to worship him.
If there are too many lists to mention, then mention at least a few authentic references with exact verses / lines.
Reason for my curiosity: Suppose I am an alien who has come to earth and started speaking understanding the language here. After spending some time with poor (having no special powers) mortal humans, I come to know that they do a lot of things for their living like the business, jobs, singing, etc. which completely makes sense.
However, they also follow some spiritual rules/teachings which is absolutely not necessary for the living. When asked for the reason, they all said they follow it to be a good human being, to be good for the society and overall peaceful coexistence on the earth. But they all varied in one thing i.e believing in different Gods (the creator of all the universe) and they all claimed to be true.
So instead of believing on individual person I took all the religious books and went to search on my own who is the actual God...
