Yes, and insufficient is the same as saying "invalid." There is no "reason" to accept the premise.
There is insufficient evidence to conclude man is derivative of a primitive life form.
Not only is there sufficient evidence all available evidence points in the direction that this is the only way homo sapiens came into existence.
There is also insufficient evidence to reliably conclude that matter organizes itself apart from an intelligent agent.
Hypothesis Contrary to Fact. Matter organizes itself and there is no evidence yet that there is said "intelligent agent," ergo this statement is invalid.
As long as you are willing to admit as much, then you ought to be willing to grant admittance at least to the notion that biological entities may have a common designer
And Leprechauns dancing for too long a period MAY cause earthquakes. But there is no evidence of Leprechauns or a designer.
matter does not organize itself without intelligent design.
No evidence. In fact the laws of physics are precisely what spells out this organizing principle. The real question is why there are any such laws in the first place.
Not only so, but you ought, in term of reasonability and certitude, to hold it on at least the same level as evolutionism.
Evolution explains the fossil record. The existence of a fossil record and transitional forms is evidence. There is no evidence of ID. None. They are not on the same level, period.
If this statement is at all demonstrative of your ability to comprehend the English lanuage and argue effectually you will never make a good apologist for the philosophy of evolutionism.
Not only is there sufficient evidence all available evidence points . . .
Appently you also hold science in such low esteem that you place more faith in so-called piles of evidence than you do in direct observation and testability in the real world. Man, stay away from the science classroom.
And Leprechauns dancing for too long a period MAY cause earthquakes . . .
I suppose one may propose as much, but it would lack scientific credibility without direct observation and testing. Your creative example, however, serves as a reminder that you bear the marks of your Creator.
