Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.
it is to prevent the moisture formed due to condensation of the agar ,to mix with the components present in the petri plates, else causes contamination
During incubation of Mueller Hinton plates, bacteria colonies grow and multiply. Additionally, antibiotics diffusing from antibiotic disks create zones of inhibition around disks indicating the susceptibility of the bacteria to those antibiotics.
Bacteria love to grow in moist damp places - if you haven't noticed, condensation causes water droplets to form on the top of the lid and if you incubated the plate with lid on top when the water runs down the sides of the plate it can easily contaminate your culture.
There is always some water condensation on the inside of the lid if it's kept in the 'regular' position. If water drips back to the culture the indivodual bacterial colonies will wash together. Inverted incubation prevents that.
Placing the inverted Petri dish in the incubator after streaking helps prevent contamination from condensation dripping onto the streaked agar surface. It also helps to maintain a sterile environment by protecting the surface of the agar from airborne contaminants that may settle on it during incubation.
Condensation on agar can lead to uneven distribution of nutrients and moisture, making it difficult to interpret results. It can also provide a conducive environment for microbial contamination, affecting the purity of the culture. Additionally, excess moisture can affect the growth and development of the desired organisms.

Storing agar plates inverted helps prevent condensation from collecting on the agar surface, which could interfere with bacterial growth or lead to contamination. Storing agar plates inverted also prevents any moisture present in the lid from dripping onto the agar surface, which can disrupt the growth of the bacterial colonies.

If by 'downside' you mean inverted, the Philippines flies their national flag inverted when they are in a state of war.
Yes, ducks do not typically abandon their eggs during the incubation period. They are known to be dedicated parents and will usually stay with their eggs to keep them warm until they hatch.
