What Are Their Main Differences?
'Each' refers to every person or thing in a group of two or more objects, while 'both' refers to two options out of the two. Although these words are misused a lot, they serve completely distinct purposes. 'Each' refers to individuals separately but 'both' refers to two people or things together at the same time.
What They Refer to
To make it more clear imagine we have a group of 10 people or things. If we want to refer to one individual in this group we can use the term 'each'. But it is not always that we have a group of ten. A group can contain two or more people or things, The only important thing is to know that we are referring to only one of them.
If the group is contained of only two people or things, you use the term 'both' to refer to two of them. We mean by using the word 'both' you refer to two people or things at the same time.
