Science will allow us to do some pretty odd things but it will not be a creation from nature but an aberration, a science experiment.
Plus, it worries me what might result from us tinkering with the DNA of various species including humans. The consequences may not be seen in the first or second generations but maybe many generations. And by then, it will be too late.
One thing for sure; one does not violate God’s Laws with impunity. Somewhere down the road, there will be a very high price to be paid.
