Conception is when the egg accepts a sperm, and that's when life begins.

Please read my comments to post 1.

Conception is not an instantaneous event. Even under the microscope it can be observed as a continuous process. It consists of millions of insignificant chemical reactions.

There just is no poof. This is fact substantiated by so many observations that most scientists just take it for granted.

Earth to beavus!

Some of your proof is in post #61. Having had three children of my own, just take my word for it. Life begins at conception.

Your claim assumes that ontological changes per se are observable by scientific instruments and/or quantitative means. That assumption, however, is not true, as Aristotle showed. Physics, chemistry and biology do not determine ontology. Positivism and scientism are false philosophies. A helpful intro to philosophy book is An Introduction to Philosophy by Maritain.
