Translation of "perhaps" into Portuguese

Other life probably exists out there and perhaps in many places.

Outras formas de vida provavelmente existem lá fora e talvez em muitos lugares.

In this world, perhaps. But in my world the books would be nothing but pictures.

Neste mundo, possivelmente, mas em meu mundo os livros não seriam nada sem imagens.

A bird in the thicket had been repeating one and the same note, perhaps calling to its mate.

Um pássaro cantava na espessura do bosque, repetindo a mesma melodia, quiçá chamando a companheira.
