Isn’t there a quantum theory of entanglement that says something like once two electrons meet then separate they are still ‘bound’ and influencing each other ?

Isn’t there a quantum theory of entanglement that says something like once two electrons meet then separate they are still ‘bound’ and influencing each other ? I wonder since, as carbon based life forms , we are all just made up of stardust , how and on what string theoretical levels we are quantum entangled with all the atoms known as planets moving around ?
