This is a lie as there is no scientific consensus that a fertilized egg is a person. A fertilized egg can grow into a person, but a fertilized egg has no organs no brain, no capacity to feel or think, etc. At that point it is just two cells.
I don't know what scientists you are talking about, but without consensus they are meaningless, and there is no consensus.
Bring in creationism now. We don't consensus there either.
