How do we prove things exist?

• Personal experience - 'I've seen it'
• Reliable evidence - ' I haven't seen it but other people have convinced me that it exists'
• Chain of reasoning to reach a conclusion - 'I haven't seen it but there must be a logical reason to believe in its existence'

Example: The Loch Ness Monster:

• People have seen it 
• People accept acocunts and evidence of sightings from other people
• With all the sightings it seems more likely that there is one than isn't

People reject it because:

• No evidence for themselves
• Don't accept other evidence-think it's lies,hallucinations,mistakes,wanting to fool others
• They think that without any proof it's not logical to accept its existence

How do we prove God's existence?:

• People are certain…
