People say "VPC is region specific - meaning vpc exists in the region in which it was created". Is it true? If so, why create-vpc doesn't have an option to choose region? What if I want to replicate a VPC in multiple regions?

Yes
create-vpc doesn't have an option to choose region
By default the user's default region is used, possible to override using the --region parameter.
The --region parameter belongs to the aws cli level (not just ec2), so it is documented elsewhere
What if I want to replicate a VPC in multiple regions
I'm not sure what do you mean by replicate, you may create a vpc with the same properties in each region. Each vpc is region-specific, so the VPCs in each region are separate and not connected whatsoever.
It is possible to connect multiple VPC in different regions using VPN or Inter-region VPC peering. Anyway I'd advice to keep systems between regions separate or use aws-native replication if really needed.
