I've seen a couple of miracles in the last 10 years (and I'm not making a joke either like it's a miracle I got married).
I'd suggest that you just haven't heard about them.
In case you're interested I've seen a friend's back problem (that was caused by one leg being longer than the other) cured by being prayed for in church. The leg grew to the same length as the other. My other best one was with a lighting desk that wasn't working and that the owners wanted us to confirm wasn't working so they could press their case for buying a new one. Well, it wasn't working and we couldn't make it work. We prayed about what to do and then tried it again (not doing anything different than before) and it worked fine. In both cases I talked to the relevant people a year or more after and they were both still fixed :)
Through links with church and other christians I've heard of other miracles and regularly have impressive answers to prayer that could be considered little miracles. Certainly enough to challenge the argument that they could have just been coincidence.
So, sorry that that's another story about miracles for you but it's what I saw.
