What you are trying to call evidence for anything is actually just speculation. First you can speculate that abiogenesis is possible without having the slightest bit of evidence that it is. What makes you think this is even possible?
You seem to be confusing science with history.
We don't have evidence of the exact pathway by which abiogenesis occurred just like we don't have inch-by-inch evidence of the route that Lewis and Clark took to the Pacific Ocean. But it isn't speculation to say that it's
possible to reach the Pacific Ocean.
The existence of the Eiffel Tower is evidence of the possibility of building a 900-foot tower, even if we don't know the exact order in which the parts were assembled. Similarly, the existence of complex molecules is evidence of the possibility of making complex molecules, even if we don't know the exact pathway by which they originally
did assemble. The fact that living organisms
can assemble complex molecules out of simple components is further evidence that the necessary conditions do exist.
We can reasonably conclude - not speculate - that water has the same freeze/thaw/evaporate/condense behaviour on other planets as it does on earth. We can similarly conclude that other chemicals, the constituents of life, have the same behaviour on other planets as they do on earth. Hence, it is inevitable that abiogenesis
will happen, given the appropriate conditions. And considering the size of the universe, it seems quite likely that those conditions do arise from time to time in one place or another.
Edited by ringo, : Changed "biogenesis" to "abiogenesis". Freudian slip?
