This is such an interesting question.

If the alien civilization published a single block (at the leading tip of the chain) with 100 leading zero bits, it demonstrates they channeled more than 2^20 times or roughly 1 million times the amount of energy in the entire bitcoin hashing network into that block or roughly 1000 times the total electricity output of humanity (assuming bitcoin consumes 0.1% of total world electricity).

It also shows that the aliens want us to know how powerful they are and that they exist since they could have simply mined a winning block with not as many leading zeros. More interestingly it demonstrates that they mined that block within close proximity to us; at most, 5 - 10 light minutes away.

I would start by waiting to see if they published more similar blocks and hence try to adjust the difficulty upwards by a lot.

If not, I would put a message in one of the subsequent blocks asking to establish trade and communication with the aliens. Any race that can channel this much energy into this calculation must have invented their own version of sound money that can't be fucked with. This answer hasn't begun to scratch the surface of the consequence of an event like this happening though.
