Jeez - here we go again.
There is NO EVIDENCE of any human intervention, terrorists, hijacking, rogue pilots, suicides or alien abduction.
The tiny amount of VERIFYABLE evidence simply tells us that something went badly wrong. Apply a good dose of Occams Razor and the simplest explanation is a catastrophic depressurisation, probably due to a structural issue.
Cargo door, cockpit windshield, upper skin panel ...... many more possible.
Even a birdstrike is possible - it has happened before at 37500 feet but I doubt if vultures would be flying at night.
