You misunderstand. The *conclusions* will be approximately the same. But there is no fundamental requirement that, say, Newtonian physics must begin with the statement of Newton's Laws. To give a simple example from mathematics, there are different sets of axioms that lead to Euclidean geometry. Are you quite certain that there is only one way to explain what explained?
And you are ignoring altogether the possibility that an alien physics may be based on insights that are deeper than ours. Are you quite certain that no alien physics can have successfully combined our Relativity and Quantum Mechanics to resolve what we see as their differences?
You seem fixed on the notion that *you* have the right answers and nobody else possibly could.
