If you hear the starter, click, either we have a faulty battery, a weak battery connection, or the engine is locked.
Do me a favor. Try this very simple load test on the battery. You don't need any tools. Additionally, make sure the battery terminals are both clean and tight.
Also, let me know approximately where you hear the humming sound coming from and if there were any issues with the engine prior to this issue. For example, were there any knocking/ticking sounds from the engine or was there a noticeable power loss?
One last thing. See if it makes a difference if you try starting it in neutral.
Let me know what you find.
