So the position that God or some other intelligent being directed life is a "*huge* leap", but it happening on it own with no theory and no repeats is not?
Life is a complex chemical process. The basic building blocks are common in the universe and spontaneously form the types of structures that would be expected in the early stages of the formation of life.
The life we have *today* shows the remnants of previous metabolisms based on RNA.
So, yes, the idea that the chemical process of life can come about via chemical processes that existed on the early Earth is a reasonable *hypothesis* to test.
On the other hand, to postulate an intelligent being involved begs the question of how that intelligent being, which would clearly be very complex, came about. It simply pushes back the same questions of the origin of life to another location that we have no evidence for, not way of determining the conditions, and no way to test the ideas. Furthermore, we have no idea of the metabolism of this creature, no evidence such creatures exist, no idea how its intelligence arose, and no way to test *any* of those notions.
Furthermore, it fails to address *how* that intelligence directed the beginning of life on Earth. What techniques were used, what precursors, what steps were taken?
In other words, the intelligent direction theory doesn't even answer what it sets out to explain, let alone address the numerous other questions that immediately arise.
So, yes, it is a MUCH smaller leap to say life came about through testable chemical processes that we can see even in life today than it is to postulate an unknown and unknowable intelligence that directed everything.
If you cannot see why that is a smaller leap and just how large the leap is for a directing intelligence, you need to sit down and learn a bit more science and how to go about testing ideas.
