You're being simplistic about origins. I am far from inattentive, but instead disagree.
You speak of lack of evidence( yet you have given none for your views) and how there are many paths (which I definitely disagree).
What I do know of Buddhist beliefs is there is No God, thus No Heaven, which means the end is not the same, but instead "Nirvana" which is on earth. That is not another path to the same end, but instead more of a parallel path. BUT parallel lines never meet ( and in that I am being simplistic). The origins of Buddhism are far more intangible, and with far less proof.
If a Pope compiled the writings, good for him (and yes that has a basis in fact), but that was far from the beginning of the belief structure. The EDITING you speak of, I have spoken of as well. The editing has been checked and rechecked over generations with original documents, and found to be uncannily spot on. It started with Adam, and the first compilations start with Moses. Many authors through a long time span (not one book written LONG after the death of Buddha) put down info from their events, and strangely enough the writers agree, all the way from Genesis to Revelation. In fact Genesis even has reference to Revelation events. Go figure.
I have laid out some trues and PROOF, but if you don't want to check the points out, so be it.
BUT , I have not been inattentive. No contradiction, No hate. A bias? Yup!
As I say, you have not been paying attention as shown by your insistence that there be an end game, a reward, an everlasting life. You also seem to lock onto Buddhism even though I only use it as one example.
And you seem to believe that all the writing and editing have been checked and rechecked and all seem to agree. They don't. Some agree with some of the CHOSEN original documents but don't agree with other contemporaneous documents of the time that contradict those CHOSEN documents.
Just look at the 10 Commandments as a most basic example. Religious scholars have at least twenty variations of that single text and some can't even agree if it should be canon or if it is not relegated to "guidelines".
Then look at Adam and Eve, the ROOT of the Bible, the Genesis as it were. Two Adults with two Boys. Yet, from them sprang the entire civilization. In the Fundemental, Charismatic Christian world of Biblical Inerrancy that means there was some serious incest. But wait. There were the people of...some other subdivision, maybe...but we really aren't told about them since we are told only about A&E.
Then there is Noah and his clan after the flood. Now Noah and his three sons and their wives would have had offspring. Guess what happens next?
Inconsistencies and contradictions. The message from the Bible should be: Be a good person and take care of those who can't take care of themselves. Period. Everything else is parable and legend and should be looked at in that light. There are folks that take Star Wars too literally also.
