That struck me as mostly reasonable until the 'playing god' bit which upended everything. For one, that term almost never means the same thing to any two people. For another, from the context up to this point you seem to have unrealistic assumptions that this is all part of a broader cosmic give and take that balances itself, or stands over us as an indecipherable mystery. I think that temptation to stand in awe before a cosmic mystery is a common one and, in many cases a laudable one. In this case, that temptation is getting in the way of some very-knowable facts which are spelling out doom. "Not playing god" in this context seems to amount to standing by as an extinction event unfolds, and I don't think the desire to get lost in existential ditherings is an acceptable reason to stand by and let that happen.
