A graphic artist created this illustration: https://www.dreamstime.com/boy-light-ball-looking-fantasy-tree-night-scenery-boy-light-ball-looking-fantasy-tree-digital-art-image100502024 .
Then, someone created an animation out of the illustration: https://www.youtube.com/watch?v=1GBfVhmrvhQ&lc=UgwV3DHioL_3ceLfj4J4AaABAg (background animation). Is it possible that someone else (than the original artist) did this animation, without having the vectorial file?
For the illustration, Photoshop is the best tool for this. For the animation, there are many apps that can make a simple animation from chosen photo, you can search in your phone's app store
