Did Latin originate from Greek? Also no. They do, however, share the same origin. Both Greek and Latin belong to branches of the Indo-European language family, which does not necessarily make them all too similar, since these two branches are radically different.

What is the difference between Nosco and Cognosco?

Nosco is obsolete in Classical Latin since it is statice and always appears in the perfect tenses (e.g. odi 'I hate'). Novi means 'I know someone' i.e. acquaintance. Finally, cognosco means 'I recognise' in the sense of perception or realization (sentire also has this meaning).

What language is Latin derived from?

How similar are Latin and Greek?

The obvious syntactic similarities between Greek and Latin are mostly due to their both being fairly conservative Indo-European languages. Lexically they're not very close at all. Nowadays everyone categorizes them as being in fully separate branches of the Indo-European family.
