Get along little doggie

It is my belief when God's defining word ie the bible and the religions that at there core structure they are all basically the same. I mean to say what are the problems we all face in getting along.

I mean really people every religion I have hearrd of has alot of similarities the easiest one to quote and compare for similarities are the laws of not killing,stealing,worshiping false gods,etc.

Well there is another I know of 5 or 6 religions for example there Jesus equivalent in physical form looks almost the same, and was born to this earth into flesh and died of that flesh and rose in spirit to return and save
the children of God from their destruction and to punish them that tresspass against his children...

This all being the case why cant we all get along and respect each other.
