I'm trying to learn dns and bind on centos 7 at digital ocean. When I run named-checkzone
I get the same errors. When I change around the white space I stop that error only to replace it with a 0 SOA and no NS error.
sudo named-checkzone example.com /etc/named/zones/example.com.zone

As Julie Pelletier already commented, remove the leading white spaces in your zone records, as they hold a special meaning in Bind zone files.
By starting a line with a white space (which is neither a hostname, the zone name or the @ shorthand for the zone origin) that line becomes a continuation of the record above it.
That makes the line with the SOA record a continuation of the none existent record above it (the variables don't count in that regard) and hence your failure; there is resource record above it, no owner to apply that continuation record to.
You can intentionally use lines starting with a white space to though:
