As for ID, it is fully testable and disprovable, to disprove it you should have to show using objective evidence that the simplest forms of life arose from a naturalistic cause rather than an intelligent cause...to this date (since the 1950s) no one has been able to prove a naturalistic explanation which is why panspermia is becoming more popular
Panspermia has gained ground for a number of reasons, but not at the expense of a naturalistic cause for life. Even if Earth's life came from somewhere else, life still had to start somewhere.
We are able to create light-reactive, growing, reproducing spheres in the lab. we are able to create organic compounds from inorganic compounds in the lab. Not full cells, certainly, and not anything complicated enough to call life, no. But the building blocks are in place, so I don't see the leap from where we are to a full man-made cell to be anything more than a gulf in time and effort.
If/once man creates a cell, however, people who believe in creation will certainly just start arguing that since man could create, then clearly God did too. It's not a reasoned position, and does not include a falsafiable threshold where the idea would no longer apply to a different, incompatable dataset.
It is not, in that manner, ever "wrong", as it's correctness cannot be tested (by design), however, neither is it ever "useful".
for those who aren't familiar with the formal study of Logic, this:

I'll give you an example of how you are wrong. Can I prove that there is not an elephant in space anywhere in the universe?
No, of course not, not without searching the entire universe. Hence why science depends on experiments done for means of falsifiability. You come up with an idea, for example that evolution through mutation and natural selection can produce new, different creatures, and then you go and see if it can, for example by the mutations of fruit flys.
giving about a specific example of the practice of generalization; without a solid understanding of the idea, and why inductive reasoning is useful, then no amount of fruit-fly examples will make a lick of sense.

If we pull 95 marbles out of a bag of 100, and all of them are red, we can inductively gather that there is a high probability that *all* the marbles in the bag are red. We can't say for certain, as a single yellow marble would invalidate the theory (at which point we would still be able to say "nearly all the marbles in the bag are red"), and until we have pulled out every marble, we don't know if there are any yellow marbles or not. However, the chances of pulling 95 red marbles in a row out of a bag containing 95 red and 5 other-colored marbles is so small that the chances of the bag containing only 5 yellow marbles at this point are close to insignificant.
In cases where we need to make a choice in life based on the pull of the next marble, pure randomness offers us little hope of making anything but a foolish decision. In the cases where inductive reasoning allows us to use generalization to make informed (though certainly not always correct) decisions, it is *useful* for use to do so.
To simply say "I refuse to make a generalization on the next marble pull until I see all 100, then I'll know for certain" would be a nice way to go about life, if we expected to live forever and eventually know everything. Until we are what creationists consider God.
Until that point, we have science to help us make effective and useful choices, based on the most recent number of marble pulls so far.
