It is good to be aware of what we think is goofy. Then ask why we think something is goofy or not.
I agree with you that the Earth is not flat. One can perhaps guess that by looking at the stars circling us and seeing that other planets seem round enough. But to ask whether something is conscious or not is not so easy to decide. One has to look at the objective measurements of the object and from that wonder if the object has a subjectivity of any sort. The only reality we know for sure that has a subjectivity is ourselves because we can experience our own subjectivity.
One way to look at the objective measurements is to ask if there is anything that appears "random". Now it may be random because we don't know what determines its behavior yet. However, it may be random because it is making choices. Randomness would be one way subjective consciousness appears in objective data especially randomness that is not uniform, that is, not like flipping dice.
You're asking a good question about the level of consciousness of an electron and a mosquito. Sheldrake asked something similar with regards to how conscious the sun is with respect to us. I think the mosquito would have a more complicated level of consciousness than an electron because it is a more complicated self-organizing object. However, one can quickly reach a conclusion that the electron is conscious if one interprets quantum indeterminiism ("randomness") as making choices. Admittedly this is precisely why there are so many interpretations of quantum physics. They all want to get around the idea that the electron made a choice. Some of those interpretations are pretty bizarre such as many worlds.
So it goes back to what one finds goofy. I find it less goofy to think the electron made a choice (that is, the electron is conscious) than to believe in parallel universes or many worlds.
Some people today think that perhaps sometime in the future an AI computer will be conscious. Is that a goofy idea or not? And what motivates one to think of it as goofy or not. In my case, I would say that because the computer is not making a choice, evidenced by it having a programming, that it is not conscious.
