Translation:Wij wonen op de planeet Aarde.
You're right, thanks for mentioning. Next time please use the report a problem button to report mistakes or alternative translations.
I wanted to know by first hand that maan and aarde didn't have capitals, but yes, sorry, I forgot to report it too! Thanks for the confirmation anyways!
No problem. BTW zon also is written without caps, together with aarde and maan they are the only exceptions I think. All other celestial bodies are written with a capital letter.
