2005 Mazda 3 wont start
 

Cars been sitting in a garage for a while and i have no idea whats wrong. It sounds like the starter is the issue but it could also be the battery.

Took this video https://www.youtube.com/watch?v=o8OifgEC8XU

It sounds like it tries to turn over at the start but then it just starts clicking. Looking to get a second opinion on what it might be before i go and buy a new battery or starter.

This video was taken after i tried to jump start it. Not sure what to make of the sounds im hearing so thoughts on this would be appreciated.
