I don’t think that humanity will exist forever, like other biological kinds it can disappear or transform in something that impossible to identify with humanity. But I think that the Universe (the sum of all what exists) is infinite and eternal, and Big Bang, which brought into existence our observable astronomical space, is just local event in the endless surrounding Universe. The Universe can't be finite in time (in the past), otherwise the birth of the Universe is an event without any cause. If the Universe is infinite then possibly there is something that requires googological numbers for measure.
