You are missing the point still. The question was whether the presence of appendages convenient for tool-making is an important factor in intelligent species' ability to build a technological civilization. In other words, whether creatures intelligent enough to build a technological civilization, but lacking an equivalent of hands, would still manage to build a technological civilization.
Elephants or crows are irrelevant, as they are not smart enough. Human use of tools is irrelevant, as we do have hands. The relevant class of creatures are those that are smart and don't have hands (or similar), for example having bodies of tortoises (or worse).
Hmm, I'm confused now about what you are trying to assert. You are, if I'm now parsing you correctly, asserting that a species with no tool appendage but with some version of the scientific method could reach a high tech level without tool use? If so, that doesn't seem unreasonable, but you seem to be conflating intelligence with having a scientific community. These are not at all the same thing.
