Is Google Translate reliable?

[SDMBKL]

I was playing with Google Translate, and for no apparent reason, I translated text to Latin. I studied Spanish as a foreign language in grade school, so I knew how Romance languages work. They work VERY similar to English.

I typed this into Google Translate:

To think
I think
You think
He thinks
She thinks
It thinks
We think
You all think
They think

And I got this as an output:

cogitare
puto
putas
cogitat
putat
putat
nos cogitare
Vos omnes putant
putant

Based on my knowledge of Spanish, to think would be pensar, the conjugation would be pienso, piensas, piensa, pensamos, piensais (accent on the a), piensan. So, why is Google Translator giving me this seemingly incoherent jumble of conjugations? Is the Latin conjugation correct?
