Multibit 0.5.14 is a MultiBit classic version which does not have seed words and does not support Hierarchical Deterministic wallets. So long as you know the password to your wallet and you have an up to date backup of it, you will be able to access your Bitcoin. There are no seed words for you to recover.
However, MultiBit 0.5.14 is an extremely old version of MultiBit. It is a version of MultiBit classic which was deprecated and replaced with MultiBit HD (which has seed words). Furthermore, MultiBit HD is no longer maintained and supported. So your version of MultiBit is several years out of date, contains potential vulnerabilities, and is no longer maintained whatsoever. I would highly advise that you switch to using a different wallet software such as Electrum.
