I have memories from before I was born. The earliest is my first recollection of consciousness.
Have you ever been in the countryside, and suddenly heard distant church bells? And when you heard them, you realise that there were several peals *before* the one you actually heard, that you are hearing now, in retrospect?
Well, it was like that. I woke up, and at the same time I realised I had been awake before. And also that because I could remember having been awake before, there was a connection between these states of wakefulness, and that connection was me. Wow! I existed!
Now as every good scientist knows, people can't remember that far back, so clearly this is a false or manufactured memory. This is convenient, because if it were a true memory, it would give the lie to the belief that consciousness requires language, since it would mean that I was conscious before having any language. And it's helpful too because you can treat animals like automata, since, although they clearly react to pain, they don't actually *feel* it in any conscious way, having no language. Dead handy for experiments.
And everyone knows that rocks don't fall from the sky, either.
