Where is the ground in your first video ??. Because you said ' ....dust falling to the ground' but show something completely different, totally dishonest, lmao. How do you know there's no air or water current or what ever that may be acting on the dust ??. You don't. Where and when was the video taken and under what conditions ?? - you don't even know that neither does the video tell us. The second video shows a short few second clip where-as the long versions of moon-dust and buggy spray completely disproves their hypothesis/ opinion.
