Aliens seeded the earth, goddidit, both of these would presume that all life is going to be similar in construction. The evolution theory is no different than those other beliefs in regards that falsification parameter.
The general evolutionary mechanism could be falsified if it could be shown that there is no mechanism of inheritance, or that there is no such thing as differential reproductive success(natural selection), or no such thing as random sampling(genetic drift). These are all theoretically possible observations, but they have not been made, which is why the theory is falsifiable but not falsified.
Now that is just silly. All of our history of life shows inheritance. We have no mechanism to create life from non-life.
Basically what you said here, was if we figure out how to create life from non-life, that evolution is falsified. You don't believe that, but that is where your logic takes you.
