macOS Extra Window Opens in Browser

[thriftinkid]

Here is probably a dumb question. The script I have below works. It just opens my URL in a new window of Safari instead of loading it into the default window when Safari Opens. How do I resolve this?

set theURL to "http://www.mywebsite.com"
tell application "safari"
open location theURL
end tell

Try this:

set theURL to "http://www.mywebsite.com"
tell application "Safari"
    set URL of document 0 to theURL
end tell
