We also cannot prove the exact force behind gravity (see the latest thread on theories of gravitational waves), yet we don't go flying off the face of the earth when we jump, do we?
Also, thanks for letting me have your vaccination shot against the avian flu when we develop one. You obviously don't believe it would ever be a threat, since it would have to - get this - evolve.
Gravity can be observed real time.
Are you saying we can't CREATE viruses in the lab? If we can do it, can't God create as well?
That's right. You don't believe in God. That's your choice.
