I am obviously talking about Avengers: Infinity War Thanos, who died in the beginning of Avengers: Endgame.

How old was he when he died? I am seeing all over the internet that he was thousands of years old, but I don't see any proper citation.

I saw his earliest footage when he was conquering Gamora's planet, but that should be few decades ago at most, because Gamora was little kid at that time.

How old was Thanos when Thor chopped his head off? Any words from writers/ directors/ producers or any educated guess?
