This pair of long videos from Melodysheep are a stunning audio-visual experience about the prospect of alien life somewhere in the universe. They may well provide inspiration for your own projects and I can certainly recommend watching them both when you have time.
If you do watch these videos and appreciate them then I would also suggest that you consider using Patreon to reward the artist. Relying on ad revenue alone is not the most reliable way to ensure content like this continues to be created.
