Well to date there is a lot more evidence for UFO's and alien big cats than for Saddam's WMD's.
Seems we pick and choose what we mean by proof.
I have put a link with interesting evidence on in my introduction thread.
But I have seen several large black cats in a huge nearby forest. Problem is I don't tend to carry my camera on horseback and that is generally the only way they will get relatively near. Same with deer. Regularly ride among a herd of deer without them batting an eyelid. Have also seen
Red Deer there and they aren't supposed to be there either. My horse isn't so keen on getting close to him.
A Quantox Hunt had a lynx up a tree a few years back.
The trllech panther is our local one and I don't know many country folk who haven't seen it: because there are almost certainly more than one over a huge expanse of monmouthshire and forest Of Dean.
A few cases of rotting dog carcasses up trees too.
Smell. They have a strong scent.
The problem is that the few "official" investigators haven't found hard evidence. But that doesn't stop live and dead spcimens turning up from time to time. The Surrey Puma for example.
I think UFO's may have a variety of causes. Some natural phenomena we don't yet understand. There is lots of evidence of sightings, pics etc that have been shown not to be fraudulent. The issue is whether that means they are space vehicles or not. A more likely explanation would be inter dimensional vehicles; or "natural" inter dimensional traffic. If that sounds far fetched please tell me why this is being done at a cost of £6 billion. That isn't scientific curiosity.

Worth remembering in all this that the legendary "wild man of the jungle" who would stand up in the bush and beat his chest, was refuted by science for years. Then he turned up in the late 1800s and science called him the Gorilla.
Science dosn't know a fraction of what is out there in terms of wild life. I can take you to parts of Wales where they swear there are dragons. They shut up about it when strangers come as they know they will be ridiculed.
