How do I set key binding for set mark in emacs?

I'm trying to set Meta + spacebar to set the mark for highlighting text (at current cursor position). searching around online and experimenting I've ended up with the command

(global-set-key (kbd "M-SPC") 'push-mark nil nil 1)

The above command isn't working for me though, I'm getting an "incorrect number of arguments error".

Got the function definition,

push-mark &optional position nomsg activate

Position: nil for position should default to current cursor position

nomsg: I don't care about (I think)

activate: apparently isn't true by default so I need to set it to...something.

How would I format the command to pass in three values?
*The error is definitely due to the push-mark function call as other functions such as backward-char (which I'm not passing inputs to) work correctly*
