These individuals assume the Homo Naledi made this ritualistic climb in a cave to bury their dead. You're not geologists you're archeologists. The whole cave structure could have been different 250,000 years ago. They could have just walked in and walked out, yet you assume way too much with no solid proof. You want to spin a narrative to fit your story. You're scientists get data before you reach a conclusion. Early on you admitted the entrance of the cave collapsed, yet you have no geologists on your team to give you data for your hypotheses. Please look at all possibilities before televising documentaries that are purely speculative.
