You have:
if Choice1 == 'Life' or 'life':
Which is actually the equivalent of:
if (Choice1 == 'Life') or 'life':
A non-empty/non-zero string ('life') will always be treated as true, hence why you end up there.
You either want:
if Choice1 == 'Life' or Choice1 == 'life':
or:
if Choice1.lower() == 'life':
