In the physical, scientific search for our origins we only have the data set found on earth.

Correct. ID people argue that this particular data set shows evidence of intelligent design.

They keep arguing that, but then they keep failing to actually show how it does.

There could, theoretically, exist data showing otherwise at some other location.

There's plenty of "data showing otherwise". Tons of things in biology don't make such sense from a design standpoint.

Of course there is! Now please quit playing (?) stupid. Discussions of this nature would yield much more fruit for everyone involved if people would quit being intentionally dense. You'll notice that the purpose of that post was not to declare that evolution was without evidence but rather to illustrate how HIS (not your) argument could be reasoned around. Please read within context from now on.
