what would be the correct usage and difference in meaning in the sentences below:
or
"It is these small steps that let us ..."
The sentence above contains a dummy pronoun phrase: "It is" is used to make descriptive statements or other statements.
Another example: "It is true that advanced mathematics is quite difficult."
"These are the small steps that let us ..."
"These are" is deictic. It means you are pointing out the small steps previously given in the text. They can come afterwards too.
Another example:
The children loved to eat bananas, oranges and apples. These are some of the fruit that are easily available in most grocery stores.
In the first sentence you insist a little on the fact that the reason for being able to do something is the possibility of taking the few small steps in question.
In the second you merely introduce those steps as being the reason. However, the difference is small and some people might not feel that it exists.
