This shows you trying to create a pool on /dev/ada0 - since ada0
is already partitioned, this is blocking writes to the raw disk
that would overwrite the partitioning layout.

This shows that you have prepared /dev/ada0p1 to contain a ZFS pool.

Try changing your create command to:
# zpool create -f -m /mnt/nas nas ada0p1
