A few questions

Because a thinking, acting nothingness is nonsensical?

I think the universe seems to be largely nonsensical. I mean, it seems either to have always existed, or to have magically been created by something which always existed, or to be part of a chain of infinite co-existence; fuck-- none of those options makes any sense. But I do know that it includes consiousness, and so without knowing absolutely why any chain of events occurs, one of the possibilities (even if slim) is that consciousness is injected somewhere along that chain.

Injected by whom? From where?

There is no reason to believe this - no evidence that consciousness did not emerge naturally.

It depends how you look at it. On the one hand, it seems of all the things we know about, only a very small % of "stuff" involves anything we'd call thinking. On the other hand, 100% of that "stuff" is known to us only through a thinking mind-- absolutely nothing is known to exist that we are not conscious of. And 100% is a statistic worth carefully considering when drawing philosophical inferences.

That does not follow. 100% of everything we know is because we can know - we are conscious. Other animals also know things - consciousness is not binary, there or not there. There are degrees of consciousness. Consider other animals that exhibit intelligence and self-awareness like dolphins, elephants, dogs, ...
