I do not intend for this thread to be in an evolution forum. It belongs in the origin of life forum.
Regarding the claim that there is no law of biogenesis, this is just plain historically and scientifically false. The theory of biogenesis was proclaimed as being a "well established law of nature" by an ardent evolutionist and abiogenesist himself, Thomas Huxley in 1870. This proclamation was declared to the entire scientific community in that day. Since this time, not one violation of this law has been observed.
I have heard these claims numerous times and they are patently false. The Law of biogenesis is observed and used in every medical facility in the world every single day. Abiogenesis doesn't exist but in the imaginations of men.
Some argue that abiogenesis today is quite different from abiogenesis of the 1800's and earlier. I disagree and can support with evidence that chemical abiogenesis was well thought out in the 1800's.
The other important fact that is being missed, is the topic of the OP as to why biogenesis is not being taught and abiogenesis is. One is a well established fact/law of nature, and the other is at best speculation. It is certainly not observable science.
Making bold claims that here is no law of biogenesis should be supported don't you think?
