Amazing to think that this is evidemce of a murder that took place 6,500 years before the birth of Christ. Classification as murder is jumping to conclusions.
There could have been a war, it could have been self defense, it could have been accidental, it could have been an execution.
Wow. I will make sure to avoid capital punishment in the societies where execution is carried out by arrow shot at the base of your spine! THAT is vicious! Usually people want to sever the neck.
