Matter is neither created nor destroyed, it only changes. What to we don't know. So i guess in that sense it is infinite.

Energy is not infinite. It is expended. Which is why things die.

Time is infinite to our understanding, but time isn't actually real, its just how our brains' correlate events to a certain moment.

The correlation between matter and energy allows things to continually change. From living to dead, from full to hungry, from quenched to thirsty, so and so forth.

We are not aware of this. If we knew time didn't exist, we could do so much more in no time at all quite literally. Also if we were aware of all the changes we make, we would not be in the world we are living in right now. Our conciousness past death is debateable, because one: no one has had the definite experience of going to an afterlife. Two: you would have to be dead to progress to an after life, which is why no one has had the definite experience of going on to an afterlife. So in all honesty, no one can say anything other. But one thing is sure, and that is we constantly change. Into what? Nobody can say.
