Just been listening to Brian Cox saying that water is a prerequisite for life on other planets. But what if life created and sustained by H2O developed into an advanced AGI that used sunlight (or light at least as source of power ) as its fundamental life force? Just saying.
Why assume that what creates and sustains us is required for them? It’s a bit like the assumption that alien life is six foot high and bipedal. Why?
PS- Excuse my ignorance, but I really don’t undrstand how biological life on Earth can emerge from a chemical process and if it can why haven’t we recreated this process?
