Hello pals :),
I found a short and cool animation explaining the creation of the world we know as Arda by Eru and co. It is very well done and I highly recommend it for people who are interested in the Silmarillion:

Also the makers of this animation are working on another project called Dagor Dagorath. You can see some teaser trailers of it here (and on their channel ofcourse):
