Setting different email address on LG G3 I am not computer savvy, I don't want you all to laugh at me. When I set up my cell phone I used the same email address that I use on my home computer.  Needless to say, I get all my emails on my cell as I do my home computer.  I don't like that.  Can I set up a different email address for my cell phone, and if I do that will that delete my email address from computer?
Obviously not. It is even possible to add a variety of email accounts on your LG G3 including personal email and work email . But for your case, simply add a new adress. Create your secondary email adress and delete the main adress (from the phone: settings > account > Google > [your address ] > delete). 

Now you have two addresses, one on the computer, the other on the phone.
