Оригинальный текст - Латинский язык - “deus mortuus est, ego non sum” or deus est...

I found this txt in web but didn't found any translations for it but "deus mortuus est" is god is dead and "ego non sum" is supposedly I am not.

I would like to know which one is writen correctly and what does they exatly mean from word to word and also meaning of them. Thank you!
