Likewise you reading this comment, who you are, the life you’ve lived - some of it will be a product of chemicals you’ve encountered. Some of it will be from thoughts you’ve had, things you’ve learned from the external world. Thoughts are also biochemical processes, our existence and consciousness is …and from the foods our mothers ate, to the flesh that makes us up - it’s all chemicals. Very little of it came from the original sperm and egg, the vast majority came after that, from the external world. We are what we’ve been, what we’ve consumed, and what we’re made of. Regardless of whether it’s deemed synthetic or not. People just don’t like to admit that, so they downvote. Because that’s something bags of chemistry can choose to do!
