yugas supposedly last hundreds of thousands of years kek. I'll just stick to astrological ages
gpt
i think they are just extended to give a sense of grandeur 

astrological dates are more 'correct' since they can be verified with the movement of the stars


that does not mean that the description of the eras is wrong, just that it may be a misinterpretation because of western understanding of the vedas... 


basically western people 'discovered' hinduism and decided they had to put it 'in order' and define concepts according to their limited understanding of it
