Yeah, that's clear.
The cloud images don't exist anywhere online prior to October 2014. Not sure what other evidence could be required.
I do have expertise in video editing and compositing, and I'm telling you that regardless of the clouds and explosion, the timeline of the video makes it impossible to have been faked, and I'm willing to put money against that claim for anyone who wants to make the video from scratch.
Your only saving grace is the clouds, while you ignoring the mountain of evidence opposing that claim.
