I didnt say you did. I asked what happens to babies when they die, because you seem to believe there is an additional dimension after death, and I wonder what would be the point if it only lived for an hour and might not be able to comprehend or even be a point if it only lived for an hour.
Your question is irrelevant. The fact that a baby dies at birth doesn't mean his/her life didn't have a purpose, nor does it mean life as a whole / existence doesn't have a purpose.
Also, I don't believe she ever said there's an additional dimension after death. She made it explicitly clear that humans are not conscious after death.
could that be because there isnt one?
That's exactly what she said.

tbh it sounds a little silly to me, believing in something because you want it to be true, rather than because it is. Reminds me of why many believe in a heaven or life after death. But at least they have something tangible like their scriptures to go off.
Is it wishful thinking to believe that the Earth is conscious?
From the link Prince Spinoza posted, which you didn't want to bother reading, or at least scanning through:
Sentience. It may be conscious in the generic sense of simply being a sentient creature, one capable of sensing and responding to its world (Armstrong 1981).
In this sense, it's not far-fetched to say that the Earth is conscious. If we fuck it up, it will fuck us up. Example: climate change. The Earth seeks balance and harmony and will react if we disrupted that balance.
Is it self-aware and self-conscious (i.e. aware that it reacts)? Probably not.
