The MB293LL is the original first generation iPad.
Apple ended update support for the iPad1 in September 2012; the final version of iOS being iOS 5.1.1. The iPad1 is obsolete - and cannot be updated to any newer version of iOS. There are no compatible Apps for iPad1 available for download from the Apple App Store.
As already indicated by GeoffFisher725, the Amazon Prime App requires iOS12 or later.
If you want or need to current Apps, requiring a more recent version of iOS, you’ll need to consider replacement of your iPad with a newer or current model. Of current models, even the entry-level iPad8 has specifications and capabilities that will massively outperform you current iPad1 - and is compatible with the vast majority of current Apps. Other models are more powerful still.
I hope this information provides helpful and succinct clarity as to your available options - and the limitations of your current iPad.
